Question

Write a java program to demonstrate all the logical and relational operators. Mention the output. Explain in proper way ​

Answer 1

Answer:

Java Operators

In this tutorial, you'll learn about different types of operators in Java, their syntax and how to use them with the help of examples.

Operators are symbols that perform operations on variables and values. For example, + is an operator used for addition, while * is also an operator used for multiplication.

Operators in Java can be classified into 5 types:

Arithmetic Operators

Assignment Operators

Relational Operators

Logical Operators

Unary Operators

Bitwise Operators

1. Java Arithmetic Operators

Arithmetic operators are used to perform arithmetic operations on variables and data. For example,

a + b;

Here, the + operator is used to add two variables a and b. Similarly, there are various other arithmetic operators in Java.

Operator Operation

+ Addition

- Subtraction

* Multiplication

/ Division

% Modulo Operation (Remainder after division)

Example 1: Arithmetic Operators

class Main {

public static void main(String[] args) {

// declare variables

int a = 12, b = 5;

// addition operator

System.out.println("a + b = " + (a + b));

// subtraction operator

System.out.println("a - b = " + (a - b));

// multiplication operator

System.out.println("a * b = " + (a * b));

// division operator

System.out.println("a / b = " + (a / b));

// modulo operator

System.out.println("a % b = " + (a % b));

}

}

Output

a + b = 17

a - b = 7

a * b = 60

a / b = 2

a % b = 2

In the above example, we have used +, -, and * operators to compute addition, subtraction, and multiplication operations.

/ Division Operator

Note the operation, a / b in our program. The / operator is the division operator.

If we use the division operator with two integers, then the resulting quotient will also be an integer. And, if one of the operands is a floating-point number, we will get the result will also be in floating-point.

In Java,

(9 / 2) is 4

(9.0 / 2) is 4.5

(9 / 2.0) is 4.5

(9.0 / 2.0) is 4.5

% Modulo Operator

The modulo operator % computes the remainder. When a = 7 is divided by b = 4, the remainder is 3.

Note: The % operator is mainly used with integers.
