1、匿名類物件的呼叫，僅僅使用一次；

new objectname（）.method;

2、可變引數 String ... args

package com.test.args;

public class TestArgs {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		new TestArgs().sayHello();
		new TestArgs().sayHello("suwenqing");
		new TestArgs().sayHello(new String[]{"hello world","hello beijing"});
		

	}
	
	public void  sayHello()
	{
		System.out.println("hello world");
	}
	
	public  void sayHello(String args)
	{
		System.out.println(args);
	}
/*	
	public  void sayHello(String[]  args)
	{
		System.out.println(args);
	}
*/
	public  void sayHello(String ... args)
	{
		for(int i=0;i<args.length;i++)
		{
			System.out.println(args[i]);
		}
		
	}

}
