Overridepublic String toString(){...} 如果拼写错误，如写成"toSting()"，编译器会立即捕捉到这个错误，提示你方法名不正确。如果不使用"@Override"，即使方法名拼写错误，编译器在默认情况下也不会报错，它会将其视为新的、未重写的方法。因此，正确使用"@Override"可以增强代码的可维护性和一致性...
The Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures. This means that methods within a class can have the same name if they have different parameter lists (there are some qualifications to this that will be discussed in...

Override 的作用是：如果想重写父类的方法，比如toString()方法的话，在方法前面加上@Override 系统可以帮你检查方法的正确性。Override的用法：Override：java.lang.Override是一个marker annotation类型，它被用作标注方法。它说明了被标注的方法重载了父类的方法，起到了断言的作用。
