Variable length argument implemented using array.

This Example demonstrates how we can pass variable argument using array, but this approach is old. Now a days we use Varargs feature included in J2SE 5.

class VariableArr{
public void Test(int[] arr)

{ System.out.println("No. of args "+arr.length+"contents ");

for(int i : arr)

{ System.out.print( i+" ");

}

System.out.println();

}

public static void main(String a[])

{ VariableArr va= nw VariableArr();

int a[]= {20};

int b[]={2,4,6};

int c[]= {};

va.test(a);

va.test(b);

va.test(c);

}

}
