Java: Relational Operators

December 7, 2022

Operators

Java provides quite a variety of operators which come in handy to the programmer for the manipulation of variables. One such is Relational operator in Java which we are going to disucss on this page.

The operators in java are as follows: Arithmetic Operators
Relational Operators
Bitwise Operators
Logical Operators
Assignment Operators
Miscellaneous Operators

Relational Operators

Relational operators are used in making decisions and in loops. They are used to test or define some relation between entities.

They give output as a boolean function which helps decide the control flow to decide which way to go.

Operator	Functionality	Syntax
== (equal to)	To check if two operands are equal or not, if yes, the output becomes true.	a==b
!= (not equal to)	To check if two operands are equal or not, if not, the output becomes true.	a!=b
> (greater than)	To check if the left operand is greater than the right operand, if yes, then the output becomes true.	a>b
< (less than)	To check if the left operand is less than the right operand, if yes, the output becomes true.	a<b
>= (greater than or equal to)	To check if the left operand is greater than or equal to the right operand, if yes, then the output becomes true.	a>=b
<= (less than or equal to)	To check if the left operand is less than or equal to the right operand, if yes, the output becomes true.	a<=b

Miscellanaous Operator

Arrays

Syntax with Example

Run

public class Main {
 public static void main(String[] args) {

  // create variables
  int a = 10, b = 6;

  // value of a and b
  System.out.println("a is " + a + " and b is " + b);

  // == operator
  if(a == b)
    System.out.println("(a == b) :true");
  else
    System.out.println("(a == b) :false");

  // != operator
  if(a != b)
    System.out.println("(a != b) :true");
  else
    System.out.println("(a != b) :false");

// > operator
   if(a > b)
    System.out.println("(a > b) :true");
  else
    System.out.println("(a > b) :false");

  // < operator
  if(a < b)
    System.out.println("(a < b) :true");
  else
    System.out.println("(a < b) :false"); // >= operator
  if(a >= b)
    System.out.println("(a >= b) :true");
  else
    System.out.println("(a >= b) :false");

  // <= operator
  if(a <= b)
    System.out.println("(a <= b) :true");
  else
    System.out.println("(a <= b) :false");
 }
}

Output

a is 10 and b is 6
(a == b) :false
(a != b) :true
(a > b) :true
(a < b) :false
(a >= b) :true
(a <= b) :false
