请指出此简单JAVA程序错误在哪里？谢谢

主方法少了一个大括号 还有调用boy.speak(); 方法的时候多写了一个"="

修改如下

class Father {
private int money;

float weight, height;

String head;

void speak(String s) {
System.out.println(s);
}
}

class Son extends Father {
String hand, foot;
}

public class Example4_15 {
public static void main(String args[]) {

Son boy;

boy = new Son();

boy.weight = 1.80f;

boy.height = 120f;

boy.head = "one head";

boy.hand = "two hands";

boy.foot = "two foots";

boy.speak("i am your son");

System.out.println(boy.hand + boy.foot + boy.head + boy.weight
+ boy.height);
}
}

class Son extends Father {
String hand,foot;
String speak;
}

哎 等我做完 keyiro都做出来了。。。速度快。代码一样我就不说了。。
