How to use variable arguments as an input when dealing with method overloading?
This example displays how to overload methods which have variable arguments as an input.
public class Main { static void vaTest(int ... no) { System.out.print("vaTest(int ...): " + "Number of args: " + no.length +" Contents: "); for(int n : no) System.out.print(n + " "); System.out.println(); } static void vaTest(boolean ... bl) { System.out.print("vaTest(boolean ...) " + "Number of args: " + bl.length + " Contents: "); for(boolean b : bl) System.out.print(b + " "); System.out.println(); } static void vaTest(String msg, int ... no) { System.out.print("vaTest(String, int ...): " + msg +"no. of arguments: "+ no.length +" Contents: "); for(int n : no) System.out.print(n + " "); System.out.println(); } public static void main(String args[]){ vaTest(1, 2, 3); vaTest("Testing: ", 10, 20); vaTest(true, false, false); } }
The above code sample will produce the following result.
vaTest(int ...): Number of args: 3 Contents: 1 2 3 vaTest(String, int ...): Testing: no. of arguments: 2 Contents: 10 20 vaTest(boolean ...) Number of args: 3 Contents: true false false
