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 i...

Overloading(静态多态)In contrast, reference type determines which overloaded method will be usedat compile time.(overloading中,编译后多态方法具有不同的签名。) An Example of Overriding Here is an example of overriding. After reading the code, guess the output. class Dog{publicvoidbark(){ System...

Java中@Override的作用 @Override是伪代码,表示重写(当然不写也可以),不过写上有如下好处: 1、可以当注释用,方便阅读; 2、编译器可以给你验证@Override下面的方法名是否是你父类中所有的,如果没有则报错。例如,你如果没写@Override,而你下面的方法名又写错了,这时你的编译器是可以编译通过的,因为编译器以为这个...
