增强遍历和Object多参数遍历

public class T2 {
    public void t1(Object o){//Object是任何类型，多态
        System.out.println(o.toString());
    }
    public void t2(int b,Object...args){
        for (Object c:args){//遍历args
            System.out.println(c);
        }
    }
    public static void main(String[] args) {
        String[] a={"1","2","3","4"};
        for (String b:a){
            System.out.println(b);
        }
        System.out.println("*******");
        T2 t2 = new T2();
        t2.t1(1);
        System.out.println("--------------");
        t2.t2(0,2,3,4,5);
    }
}
