Java example - using Varargs in overloading methods

The following example demonstrates how to use variable parameters in overloaded methods:

/*

 Main.java
 */public class Main {
   static void vaTest(int ... no) {
      System.out.print("vaTest(int ...): " 
      + "参数个数: " + no.length +" 内容: ");
      for(int n : no)
      System.out.print(n + " ");
      System.out.println();
   }
   static void vaTest(boolean ... bl) {
      System.out.print("vaTest(boolean ...) " +
      "参数个数: " + bl.length + " 内容: ");
      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 +"参数个数: "+ no.length +" 内容: ");
      for(int  n : no)
      System.out.print(n + " ");
      System.out.println();
   }
   public static void main(String args[]){
      vaTest(1, 2, 3);
      vaTest("测试: ", 10, 20);
      vaTest(true, false, false);
   }}

The output result of running the above code is:

vaTest(int ...): 参数个数: 3 内容: 1 2 3 
vaTest(String, int ...): 测试: 参数个数: 2 内容: 10 20 
vaTest(boolean ...) 参数个数: 3 内容: true false false

The above is the Java example - overloading ( overloading) method, please pay attention to the PHP Chinese website (www.php.cn) for more related content!
