*Method Overloading
developing the same method with different argument list is called as method overloading. The argument list should differ in either of below 3 ways-
- Type of arguments should be different.
- Number of argument should be different.
- Position of arg should be different.
ex-
class="prettyprint prettyprinted"
public class Demo {
public static void main(String[] args) {
System.out.println("program starts");
add(5, 10);//this will call add(int a, int b)
add(4.6, 10); //this will call add(double a, int b)
System.out.println("Program ends.");
}
public static void add(int a, int b){
System.out.println("add(int a, int b)");
}
public static void add(double a, int b){
System.out.println("add(double a, int b)");
}
}
output
---------
program starts
add(int a, int b)
add(double a, int b)
Program ends.
Note-
- Inside a class, both static method as well as non-static method can be overloaded.
- In java, methods can not be overloaded by giving different return type.
- java identify the overloaded method based on the arguments, it does not identify based on the return type nor 'static' keyword.
- There can't be two methods with the same method signature inside a class.
