Relational Operator

Relational operator is an operator that declare the relation between the operand with the other operand. There are: equal to, not equal to, greater than, less than, greater than or equal to, less than or equal to. Result is given of an operation that involves relational operator will be boolean (true/false). The following table shows list of relational operator in Java:

Operator	Description
==	Equal to
!=	Not equal to
>	Greater than
<	Less than
>=	Greater than or equal to
<=	Less than or equal to

Operator == and != can be applied to any type, either numeric, character, or boolean. And the four other operators can only be used for numeric and char type, to determine whether an operand is greater than or less than the other operand. Consider the following code example:

int a = 5, b = 10;
boolean c = a > b;

Here, the value of c would be false, because value of b is greater than the value of a. In general, the relational operators used in the expression (either on the decision making or looping). Here is an example of code that will demonstrate the use of relational operator in the program.

class RelationalOperatorDemo {

   public static void main(String[] args) {

      int a=5, b=10;

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

The results will be given by the above program as follows:

a == b is false
a != b is true
a > b is false
a < is true
a >= b is false
a <= b is true
