java 不定参数使用示例

public class javaTest {
	public static void test(String ...strings){
		for(String str: strings){
			System.out.print(str + " ");
		}
		System.out.println();
	}
	
	public static void main(String[] args){
		test("a", "b", "c", "ddd");
		test("a");
		test("aaa", "aaadfd");
	}
}

输出结果

a b c ddd
a
aaa aaadfd
