METHOD OVERLOADING IN JAVA

If a class have multiple methods by same name but different parameters, it is known as Method Overloading.

If we have to perform only one operation, having same name of the methods increases the readability of the program.

Suppose you have to perform addition of the given numbers but there can be any number of arguments, if you write the method such as a(int,int) for two parameters, and b(int,int,int) for three parameters then it may be difficult for you as well as other programmers to understand the behaviour of the method because its name differs. So, we perform method overloading to figure out the program quickly.

Advantage of method overloading?

Method overloading increases the readability of the program.

Different ways to overload the method

There are two ways to overload the method in java

By changing number of arguments By changing the data type m method performs addition of three numbers. class Calculation{     void sum(int a,int b){System.out.println(a+b);}     void sum(int a,int b,int c){System.out.println(a+b+c);}        public static void main(String args[]){     Calculation obj=new Calculation();     obj.sum(10,10,10);     obj.sum(20,20);        }     } 2)Example of Method Overloading by changing data type of argument In this example, we have created two overloaded methods that differs in data type. The first sum method receives two integer arguments and second sum method receives two double arguments. class Calculation2{     void sum(int a,int b){System.out.println(a+b);}     void sum(double a,double b){System.out.println(a+b);}        public static void main(String args[]){     Calculation2 obj=new Calculation2();     obj.sum(10.5,10.5);     obj.sum(20,20);     }   }
