VarArgs method samples

/**

 */
package test;
/**
 * @author Paolo

public class VarArgsTest {

 public static void method1VarArgs(int ...intsArray){
  System.out.println("length ="  + intsArray.length);

 }


 public static void method2VarArgs(String ...stringsArray){
  System.out.println("length ="  + stringsArray.length);
 }

 /**
  * @param args
  */
 public static void main(String[] args) {
  method1VarArgs();
  method1VarArgs(1,2,3);
  method2VarArgs();
  method2VarArgs("a", "b");
 
 }
}


And output is :

length =0

length =3

length =0

length =2


NOTES: Arrays  are never null (neither if method is called without any parameter )
