Java - Relational Operators

Quiz

Java relational operators are used to compare two values. These operators return a boolean result: true if the condition is met and false otherwise. Relational operators are commonly used in decision-making statements like if conditions and loops.

Java provides several relational operators that can be applied to primitive data types such as int, float, double, and char. These operators help determine equality, inequality, and relative comparison between values.

List of Java Relational Operators

The following table lists the relational operators in Java:

Operator	Description	Example
== (equal to)	Checks if two values are equal.	`(A == B)` returns `false` if A is not equal to B.
!= (not equal to)	Checks if two values are not equal.	`(A != B)` returns `true` if A is not equal to B.
> (greater than)	Checks if the left operand is greater than the right operand.	`(A > B)` returns `true` if A is greater than B.
< (less than)	Checks if the left operand is smaller than the right operand.	`(A < B)` returns `true` if A is less than B.
>= (greater than or equal to)	Checks if the left operand is greater than or equal to the right operand.	`(A >= B)` returns `true` if A is greater than or equal to B.
<= (less than or equal to)	Checks if the left operand is smaller than or equal to the right operand.	`(A <= B)` returns `true` if A is less than or equal to B.

The following programs are simple examples which demonstrate the relational operators. Copy and paste the following Java programs as Test.java file, and compile and run the programs −

Example 1

In this example, we're creating two variables a and b and using relational operators. We've performed equality and non-equality checks and printed the results.

public class Test {

   public static void main(String args[]) {
      int a = 10;
      int b = 20;

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

Output

a == b = false
a != b = true

Example 2

In this example, we're creating two variables a and b and using relational operators. We've performed greater than and less than checks and printed the results.

public class Test {

   public static void main(String args[]) {
      int a = 10;
      int b = 20;

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

Output

a > b = false
a < b = true

Example 3

In this example, we're creating two variables a and b and using relational operators. We've performed greater than or equal to and less than or equal to checks and printed the results.

public class Test {

   public static void main(String args[]) {
      int a = 10;
      int b = 20;

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

Output

b >= a = true
b <= a = false
