引元数量可变的方法

public class Test {
    public void test(String... body){

//String...代表String的数组，长度由传进来时的数组长度决定
        for (int i = 0; i < body.length; i++) {
            System.out.print(body[i]);
        }

        System.out.println();
    }
}

public class Main {
    public static void main(String[] args) {
        Test t=new Test();
        t.test("hello,","hi");
        t.test("good morning");
        t.test("good afternoon,","good evening,","good night");
    }
}

输出结果：
hello,hi
good morning
good afternoon,good evening,good night
