Relational Operators In Java With Example Program

Various type of operator in java

There Five types of relational operators in java

No	Operator	USD	Description
1	==	A == C	Double Equal to
2	!=	A!=B	Not equal to
3	>	A>B	Greater than
4	<	c<A	Less than
5	>=	A>=B	Greater than or equal to
6	<=	A<=B	Less than or equal to

1) Double Equal 

• Check the value of two operands is equal or not if a condition is satisfied then true otherwise false

Example

public class DoubleEqualoperator {
	
	public static void main(String[] args) {
		
		int a = 10;
		int b = 10;
		int c = 20;
		
		//check the value of a and b
		System.out.println(a==b);
		//check the value of a and c
		System.out.println(a==c);
		
	}
}

output

true
false

2) Not equal

• check the value of two operands is equal or not if a condition is satisfied then the true otherwise false

Example

public class NotEqualOperator {
	
	public static void main(String[] args) {
	
		
		int n1 = 34;
		int n2 = 17;
		int n3 = 17;

		//check the va;ue of n1 and n2
		System.out.println(n1 != n2);
		//check the value of n2 and n3
		System.out.println(n2 != n3);
	
	}
}

output

true
false

3) Greater than

• check the value of the left operand is greater than the value of right operand if a condition is satisfied than true otherwise false

Example

public class GreaterThanoperator {
	
	public static void main(String[] args) {
		
		int a1 = 25;
		int a2 = 45;
		int a3 = 20;
		
		//check the value of a1 and a2
		System.out.println(a1>a2);
		//check the value of a3 and a1
		System.out.println(a1>a3);
		
	}
}

output

false
true

4) Less than

check the value of the left operand is less than the value of right operand if yes than condition is satisfied than the true otherwise false

Example

public class LessThanOperator {

	public static void main(String[] args) {
		
		int n1= 34;
		int n2 = 56;
		int n3 = 89;
		
		//chekc the value of n1 and n2
		System.out.println(n1

output

true
false

5) Greater Than Or Equal To

• This operator is a combination of two operators greate than and equal
• check the value of the left operand is greater than or equal to the value of right operand if a condition is satisfied then true otherwise false

Example

public class GreaterThanorEquals {
	
	public static void main(String[] args) {
		
		int a1= 34;
		int a2 = 56;
		int a3 = 34;
		
		//check the value of a1 and a2
		System.out.println(a1 >= a2);
		System.out.println(a2 >= a1);
		
		//chekc the value of a1 and a3
		System.out.println(a1 >= a3);
		
	}
}

Output

false
true
true

6) Less Than or Equal To 

• in this operator in two operators less than and equal
• check the value of the left operand is less than or equal to the right operand value if a condition is satisfied than true otherwise false

Example

public class LessThanOrEqualto {
	
	public static void main(String[] args) {
		
		int c1 = 24;
		int c2 = 340;
		int c3 = 24;
		
		//value of c1 and c2
		System.out.println(c1 <= c2);
        System.out.println(c2 <= c1);
		
        //value of c1 and c3
        System.out.println(c1 <= c3);
		
	}
}

Output

true
false
true
