OOPS with JAVA Brief Answer Question 1.Bytecode is a low level representation of java code consisting of series of information that helps JVM to execute the code 2. Break is a jumping statement which helps to terminate the loop and continue is also a jumping statement which helps to skip the current iteration. 3. The associativity of operators determines the direction in which an expression is evaluated. 4. The two dimensional array in java can be declared as follow: int[][] a = new a[2][3]; 5. Constructor is a crucial concept in java that help us to declare object, parameterization and customization. 6. Garbage collection in java is a concept where unused reference of object is destroyed to free the memory space occupied by the object. 7. Dynamic Method Dispatch in Java is the process by which a call to an overridden method us resolved at runtime. 8. final is the keyword which is used before the variable to make constant the value of variable and finally is block which is used in exception handling that prints any statement repeatedly. 9. Wildcards are special characters that can stand in for unknown characters in a text value and are handy for locating multiple items with similar, but not identical data. 10. The process of converting the primitive data types into wrapper class types is known as autoboxing Short Answer Questions 11.Write a program to demonstrate the use of logical OR, AND, and NOT operator withsuitable example. 12.Write a java program to find the second largest element in an array. 13.Write a java program to illustrate the concepts of method overloading. 14.Write a program by using generic method to swap the positions of two differentelements in an array 15.Write a java program to find the factorial of any positive integer given by user usingrecursion 16. Explain for-each statement with suitable example. In Java, the “for-each” loop is a specialized loop designed for iterating over elements in arrays, collections, or other iterable data structures. It provides a more concise and readable way to iterate through these elements compared to traditional “for” or “while” loops. The for-each loop is also known as the “enhanced for loop” or the “foreach loop.” we can understand with the help of following code: Long Answer Questions This is the example of unchecked exception: Comprehensive Questions 20.Explain the OOP principal followed by Java. What are the restrictions when themethod is declared as static? Write a java program to illustrate the concepts of staticmethod. Java is an object-oriented programming (OOP) language, and it follows several key OOP principles, including: Regarding your question about static methods, here are some key points and restrictions when a method is declared as static in Java: Here’s a Java program illustrating the concept of a static method: Inheritance is one of the fundamental concepts of object-oriented programming (OOP) that allows you to create a new class based on an existing class. Inheritance enables a class to inherit the properties (fields) and behaviors (methods) of another class, known as the superclass or base class. The new class is called a subclass or derived class. In essence, the subclass is a specialized version of the superclass. Advantages of Using Inheritance: Different Types of Inheritance: Multiple Inheritance (Interface Inheritance): Multilevel Inheritance:
Write a program to print your full name by taking input of your first and last name. Write a program to take input of arrays elements and displays it. Write a program to take input of two dimensional arrays elements and displays it. Write a program to find the greatest number using ternary operator. Write a program to demonstrates the arithmetic operator and their uses. Write a program to swap two variable values without using third variable. Write a program that demonstrates all the functions of string in java. Write a program to sort the elements in array. Write a program to search any element in the array and if the element found then display it’s index as well. Write a program to reverse the elements. Write a program to check whether the entered number is prime or not. Write a program to print star pattern. Write a program to find out the factorial of any number using recursion Write a program to demonstrates the concept of interface . Write a program to demonstrate the concept of inheritance. Write a program to demonstrate the concept of generics. Write a Java program to create a class called Person with private instance variables name, age. and country. Provide public getter and setter methods to access and modify these variables. Write a program to print any random value repeatedly Thanks !!
C Standards Before standardization of c several compiler like turbo c or gcc compiler gives different output of same c program. Then what the solution is? The solution is the c standard that have to follow by all the compilers and produce same result. The latest C standard was released in June 2018 which is ISO/IEC 9899:2018 also known as the C11. The main() function’s void return type − See the following program − void main() {   //program code } This program will run ok if we use the turbo c compiler but other compilers throw an error that the main cannot be void. So, which one is correct? The answer is mentioned in the standards. Here are the standardization period of C language: Escape Sequence Variables, Data types and constants/literal In C programming, variables, data types, and constants are fundamental concepts used to store and manipulate data. Let’s take a closer look at each of them: data_type variable_name; eg : int age; 2. Data Types: Data types in C specify the type of data that a variable can hold. The C language provides several built-in data types, which can be categorized into four primary categories: a. Integer Types: Used for whole numbers. b. Floating-Point Types: Used for real numbers with fractional parts. c. Character Type: 3. Constants In C, constants are fixed values that remain unchanged during the execution of a program. They are used to represent data that should not be modified or modified only under specific conditions. The const keyword is used to declare a constant variable, which means its value cannot be modified after initialization. It is often used to define numeric or character constants. Example: const int MAX_LENGTH = 100; const float PI = 3.14159; const char NEWLINE = ‘\n’; Comments Comments in C are used to provide explanatory notes within the source code. They are entirely ignored by the compiler and have no effect on the program’s execution. There are mainly two types of comments in c and they are: Single-line comments: To create a single-line comment, you use two forward slashes // followed by the comment text. Everything after the // on that line is treated as a comment and is not processed by the compiler. Example: //bimstudies.com Multi-line comments: Multi-line comments, also known as block comments, are used to write comments that span multiple lines. You enclose the comment text between /* and */. Everything between these symbols, including line breaks, is treated as a comment and is ignored by the compiler. Example: /*bimstudies.com*/ Library Functions and Preprocessor Directives Library functions and the preprocessor are essential components that aid in code organization, reusability, and efficiency. They offer a wide range of functionality, such as mathematical operations, string manipulation, file handling, memory management, and more Example of using a library function: #include <stdio.h> #include <conio.h> void main() { int num; printf(“Enter a number: “); scanf(“%d”, &num); // Using the scanf() function from stdio.h to read input printf(“The number you entered is: %d\n”, num); // Using printf() to display output getch(); } Preprocessor Directives: The preprocessor is a part of the C compiler that performs text processing before the actual compilation of the code begins. Preprocessor directives start with the # symbol, and they are used to instruct the preprocessor to perform specific actions, such as including header files, defining macros, conditional compilation, and more. Common preprocessor directives:
IELTS (International English Language Testing System) Reading is a component of the IELTS exam that measures a candidate’s ability to read and understand written texts in English. It assesses a wide range of reading skills, including skimming, scanning, and comprehending written materials. One of the biggest challenge for the students is to tackle the synonyms and abbreviated sentences. The IELTS Reading test consists of 40 questions, and candidates are given 60 minutes to complete it. The test includes three passages of increasing difficulty, each with a series of questions that test a variety of reading skills. The texts used in the test are taken from various sources, including books, newspapers, journals, and magazines. The IELTS Reading test aims to evaluate a candidate’s ability to read and understand different types of text, ranging from descriptive and factual to analytical and discursive. It also assesses their ability to recognize the writer’s opinions, attitudes, and intentions and to comprehend the main ideas and supporting details of a text. To perform well in the IELTS Reading test, candidates need to have a good grasp of English grammar and vocabulary, be able to recognize and understand different text structures, and apply effective reading strategies such as skimming and scanning. The major questions types in IELTS Reading are as follows:– 1.) Matching Headings Questions 2.) Classifications Questions 3.) Matching Sentence Ending 4.) Table Completion 5.) Flow chart completions Questions 6.) Diagram completions Questions 7.) Short Answer questions The above pic is of a girl doing reading. IELTS Reading tips and tricks Your main considerations will be to manage time as you will be given time of 1hr only. In reading the main challenges for the students is to analyze the reading doing skimming and scanning.
