又学了一招——JAVA中三个点（...）的运算符，表示可变参数列表

public class ThreePoints {


	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("print none:");
		printAList();
		System.out.println("print a int list:");
		printAList(1,2,3,4);
	}


	private static void printAList(int ...in_list){
		for(int i:in_list)
			System.out.println(i);
	}
}

print none:
print a int list:
1
2
3
4
