Relational operators in java

Relational operators in Java are used to compare two variables for equality, non-equality, greater than, less than, etc. The Java relational operator always returns a boolean value - that is, true or false.Returns this Boolean value when the conditional statement is used for-ex if,else and elseif, Because relation operators are used to with conditional statement.

java has 6 relation operators

  1. (==) double equal to operator in java.
  2. (!=) non equality operator in java.
  3. (<) less than operator in java.
  4. (>) greater than operator in java.
  5. (<=) less than or equal to operator in java.
  6. (>=) greater than or equal to operator in java.

Double equals to operator in java

We use the double equal then operator to compare the equal value of two different variables.

Example

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
                int x = scr.nextInt();
                int y = scr.nextInt();
                if(x==y){
                    System.out.println("x and y values are equal");
                }
                else{
                    System.out.println("x and y values are not equal");
                }
        }
    }

Output : 

	
	
		40 //x value
		40 //y value
		x and y value is equal

Non equality operator in java

It returns true if both the operands are referring to the different objects, otherwise false.< is less than operator.

Example

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
            int a = scr.nextInt();
            int b = scr.nextInt();
            if(a!=b){
                System.out.println("x and y values are equal");
            }
            else
            {
                System.out.println("x and y values are not equal");
            }
        }
    }

Output : 

	
	
		45
		12
		x and y values are equal

Less than operator in java

Two variables are compared whether the first variable is greater or smaller than the second variable.In less than operator, but the value of variable1 is less than that of variable2(var1<)

Example 

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
            int x = scr.nextInt();
            int y = scr.nextInt();
            if(x>y){
                System.out.println("x is greater");
            }else{
                System.out.println("z is greater");
            }
        }
    }

Output : 

	
	
		40 //x value
		10 //y value
		x is greater

Greater than operator in java

Two variables are compared whether the first variable is greater or smaller than the second variable.In greater than operator, the value of variable1 is greater than that of variable2(var1>var2).

Example 

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
            int x = scr.nextInt();
            int y = scr.nextInt();
            if(x<y){
                System.out.println("y is greater");
            }else if(x>y){
                System.out.println("x is greater");
            }else{
                System.out.println("x and y are equels");                
            }
        }
    }

Output : 

	
	
		40 //x value
		56 //y value
		y is greater

Less than or equal to operator in java

Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B)

Example

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
            int a = scr.nextInt();
            int b = scr.nextInt();
            if(a<=b){ 
                System.out.println("condition true");
            }else{
                System.out.println("condition false");
            }
        }
    }

Output : 

	
	
	 45 // value of a
	 50 // value of b
	 condition true

Greater than or equals operator in java

Checks if the value of right operand is less than or equal to the value of left operand, if yes then condition becomes true. (A <= B) is true.

Example

		
    import java.util.Scanner;
    class Relation{
        public static void main(String agrs[]){
            Scanner scr = new Scanner(System.in);
            int a = scr.nextInt();
            int b = scr.nextInt();
            if(a>=b){
                System.out.println("condition true");
            }
            else
            {
                System.out.println("condition false");
            }
        }
    }

Output : 

	
	
	 25 // value of a
	 50 // value of b
	 condition false
