what is operator overloading in java

1perator overloading is the ability to redefine the functionality of the operators. Programming languages like c++ supports operator overloading

1class CalculateSquare
2 { 
3public void square()
4 { 
5System.out.println("No Parameter Method Called");
6 } 
7public int square( int number )
8 {
9int square = number * number;
10System.out.println("Method with Integer Argument Called:"+square); 
11}
12public float square( float number ) 
13{
14 float square = number * number;
15 System.out.println("Method with float Argument Called:"+square); 
16}
17public static void main(String[] args)
18  {
19    CalculateSquare obj = new CalculateSquare();
20    obj.square();
21    obj.square(5);   
22    obj.square(2.5);   
23  }
24 }

1Java doesn't support user-defined operator overloading. The only aspect
2of Java which comes close to "custom" operator overloading is the handling of
