Relational operators in Java programming are mostly used either in If Conditions or Loops. Java Relational operators are commonly used to check the relationship between two variables.
- If the relation is true then it will return Boolean True
- If the relation is false then it will return Boolean False.
Below table shows all the Relational Operators in Java Programming with examples.
| Relational Operators in Java | Usage | Description | Example |
|---|---|---|---|
| > | a > b | a is greater than b | 5 > 2 returns True |
| < | a < b | a is less than b | 5 < 2 returns False |
| >= | a >= b | a is greater than or equal to b | 5 >= 2 returns True |
| <= | a <= b | a is less than or equal to b | 5 <= 2 return False |
| == | a == b | a is equal to b | 5 == 2 returns False |
| != | a != b | a is not equal to b | 5 != 2 returns True |
Relational Operators in Java Example
This example helps you to understand the Relational Operators practically. This Java program allows the user to enter two integer variables a and b and we are going to use these two variables to perform various relational operations present in Java Programming Language

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
// Relational Operators in Java package JavaOperators; import java.util.Scanner; public class RelationalOperators { private static Scanner sc; public static void main(String[] args) { int a, b; sc = new Scanner(System.in); System.out.println(" Please Enter two integer Value: "); a = sc.nextInt(); b = sc.nextInt(); System.out.println(" Result of a > b is = " + (a > b)); System.out.println(" Result of a >= b is = " + (a >= b)); System.out.println(" Result of a < b is = " + (a < b)); System.out.println(" Result of a <= b is = " + (a <= b)); System.out.println(" Result of a == b is = " + (a == b)); System.out.println(" Result of a != b is = " + (a != b)); } } |
OUTPUT
ANALYSIS
Following statement will ask the user to enter integer values a, b and we are going to assign the user input values to respected variables.

System.out.println(" Please Enter two integer Value: "); a = sc.nextInt(); b = sc.nextInt(); |
In the next line, We checked those values against each and every relational operator we have in Java programming.
Using Java Relational Operators in If Condition
This example will helps you understand, how relational operators in Java Programming are used in If Condition. For this example, We are using two variables a and b inside the If Statement along with relational operator to perform condition check.

// Using Java Relational Operators in If Statement package JavaOperators; import java.util.Scanner; public class RelationalOperatorsinIf { private static Scanner sc; public static void main(String[] args) { int a, b; sc = new Scanner(System.in); System.out.println(" Please Enter two integer Value: "); a = sc.nextInt(); b = sc.nextInt(); if (a == b) { System.out.println("a is equal to b"); } else { System.out.println("a is NOT equal to b"); } } } |
OUTPUT
From the below screenshot you can observe that, we entered a = 22 and b = 65. It means a is not equal to b so, Second statement is printed
Let us see what will happen when we change the values. From the below screenshot you can observe that, we entered a = 12 and b = 12. It means a is equal to b so, First statement is printed
ANALYSIS
Following statement will ask the user to enter integer values a, b and they will assign the user input values to respected variables.

1 2 3 |
System.out.println(" Please Enter two integer Value: "); a = sc.nextInt(); b = sc.nextInt(); |
If Condition
If x is equal to y then statement inside the If condition block will be executed
|
1 |
System.out.println("a is equal to b"); |
If x is not equal to y then statement inside the If condition block will be executed
|
1 |
System.out.println("a is NOT equal to b"); |
