等于使用java的oop方法

Question

我需要编写一个返回true的o是四分卫的方法，o的名字，姓氏，尝试次数，完成次数，码数，拦截次数和达阵次数等于这个四分卫的相应属性。这里是我得到的，并坚持这种等于方法。有人可以让我开始用它，即时通讯新本

Answer 1

public boolean equals(Object o) 
{ 
    if(!o instanceof Quarterback) 
     return false; 
    Quarterback q = (Quarterback)o; 
    return this.firstName.equals(q.getFirstName()) && this.lastName.equals(q.getLastName()) && this.attempts == q.getAttempts() && {the rest of the variables}; 
} 

Answer 2

假设你想传递一个四分卫对象的平等工作，​​你会必须调用不同的get函数来获取o的相应信息，然后将其与对象本身进行比较。它看起来像这样。

public boolean equals(Object o) 
{ 
    if !(o.getAttempts() == this.attempts) return false; 
} 

这只是一个让你在那里开始的想法。
