In this section, you will see the use of relational operatoer in java.

Example of relational operators in java.

In this example, you will see the use of relational operator in java. We are going to use in java program equally and relational operators determine if one operand is equal to, not equal to , less then, and greater then operand.

In this java program, there is a java class name RelationalOperater. It has six method  and two integer variable for arithmetic calculation.

equalRelOperator() -- Implements  = = (Equal)operator.

notEqualRelOperatr() -- Implements  != (Not Equal) operator.

greaterThanRelOprator() --  Implements  > (Greater Than) operator.

greaterOrEqualRelOprator() -- Implements  >=(Greater Than Or Equal To) operator. 

lessThanRelOperator() --  Implements  < (Less Than) operator. 

lessOrEqualRelOperator() --  Implements  <=(Less Than Or Equal To) operator.
