Operators form the basic building blocks of any programming language. Java also provides many types of operators that you can use on demand to perform various calculations and functions, including logic, arithmetic, relations, and so on. They are classified according to the functions they provide.

Operator type:

  1. Arithmetic operator
  2. Unary operator
  3. The assignment operator
  4. Relational operator
  5. Logical operator
  6. Ternary operator
  7. Bitwise operators
  8. Shift operator

Relational operators are a set of binary operators that check the relationship between two operands, including equality, greater than, less than, and so on. They return a Boolean result after comparison and are widely used in loop statements, conditional if-else statements, and so on. The general format for representing relational operators is:

Grammar:

variable1The relational _ operator variable2
Copy the code

Let’s look at each of the relational operators in Java:

Operator 1: “equal” operator (==)

This operator checks whether two given operands are equal. The operator returns true if the left-hand operand is equal to the right-hand operand, false otherwise.

Grammar:

variable1= = variable2
Copy the code

Example:

var1 = "haiyong" 
var2 = 20Var1 == var2 is falseCopy the code

Example:

import java.io.*;
class GFG {

	// Main driver mode
	public static void main(String[] args)
	{
		// Initialize variables
		int var1 = 5, var2 = 10, var3 = 5;

		// display var1, var2, var3
		System.out.println("Var1 = " + var1);
		System.out.println("Var2 = " + var2);
		System.out.println("Var3 = " + var3);

		// Compare var1 and var2 and print the corresponding Booleans
		System.out.println("var1 == var2: "
						+ (var1 == var2));

		// Compare var1 and var3 and print the corresponding Booleans
		System.out.println("var1 == var3: "+ (var1 == var3)); }}Copy the code

The output

Var1 = 5 
Var2 = 10 
Var3 = 5 
var1 == var2: false 
var1 == var3: true
Copy the code

Operator 2: the “not equal” operator (! =)

This operator checks whether two given operands are equal. It does the opposite of what the equal operator does. Returns true if the left-hand operand does not equal the right-hand operand, false otherwise.

Grammar:

variable1! = variable2
Copy the code

Example:

var1 = "haiyong" 
var2 = 20var1 ! = var2 is trueCopy the code

example

import java.io.*;
class GFG {

	// The main driver method
	public static void main(String[] args)
	{
		// Initialize variables
		int var1 = 5, var2 = 10, var3 = 5;

		// display var1, var2, var3
		System.out.println("Var1 = " + var1);
		System.out.println("Var2 = " + var2);
		System.out.println("Var3 = " + var3);

		// Compare var1 and var2 and print the corresponding Booleans
		System.out.println("var1 == var2: "+ (var1 ! = var2));// Compare var1 and var3 and print the corresponding Booleans
		System.out.println("var1 == var3: "+ (var1 ! = var3)); }} ** output ** ' 'Java Var1 =5 
Var2 = 10 
Var3 = 5 
var1 == var2: true 
var1 == var3: false
Copy the code

Operator 3: greater than operator (>)

This checks whether the first operand is greater than the second. The operator returns true when the left-hand operand is greater than the right-hand operand.

Syntax:

variable1> variable2
Copy the code

Example:

var1 = 30 
var2 = 20Var1 > var2 is trueCopy the code

Example:

import java.io.*;
class GFG {

	// The main driver method
	public static void main(String[] args)
	{
		// Initialize variables
		int var1 = 30, var2 = 20, var3 = 5;

		// display var1, var2, var3
		System.out.println("Var1 = " + var1);
		System.out.println("Var2 = " + var2);
		System.out.println("Var3 = " + var3);

		// Compare var1 and var2 and print the corresponding Booleans
		System.out.println("var1 > var2: " + (var1 > var2));

		// Compare var1 and var3 and print the corresponding Booleans
		System.out.println("var3 > var1: "+ (var3 >= var1)); }} ** output ** ' 'Java Var1 =30
Var2 = 20
Var3 = 5
var1 > var2: true
var3 > var1: false
Copy the code
