public class Test2 {

	public static void main(String[] args) {
		People a = new American("Jonny");
		People b = new Chinese("李小龙");
		People c = new Chinese("成龙");
		People[] p = new People[]{a,b,c};

		for (People people : p) {
			System.out.println(p);
		}

	}
}
class People{
	private String name;
	public People(String name) {
		super();
		this.name = name;
	}
	
	public String getName() {
		return name;
	}

	public String speak(){
		return "说话";
	}

	@Override
	public String toString() {
		
		return "不知道哪里人";
	}
	


	
}

class Chinese extends People{

	public Chinese(String name) {
		super(name);
		
	}

	@Override
	public String speak() {
		
		return "我说中国话";
	}

	@Override
	public String toString() {
		
		return "我叫"+getName()+"我来自中国";
	}
	
	
}

class American extends People{

	public American(String name) {
		super(name);
		
	}

	@Override
	public String speak() {
		
		return "I'm speak English";
	}

	@Override
	public String toString() {
		
		return "My name is "+getName()+",I'm from American";
	}
	
}

如上所示，输出结果是：
[Lcom.exam.zsq.People;@15db9742
[Lcom.exam.zsq.People;@15db9742
[Lcom.exam.zsq.People;@15db9742

请问我重写的toString方法为什么不生效？

方法重写的注意事项，返回值类型相同或者有子父类关系

一楼说的很对，代码对敲敲

for (People people : p) {
            System.out.println(p);   //要输出people
        }

你输出的是数组,而不是当前对象

懂了懂了，谢谢
