Java方法重载(Method Overloading)小记 方法重载概念 如果在同一个类中,两个或多个方法的参数不同(参数数量不同、参数类型不同或两者都不同),并且它们具有相同的名称,这些方法称为重载方法,这一特性称为方法重载(Method Overloading)。 要点说明 要在同一个类中(在不同的类中不算 要有两个或多个方法(只有...
Method Overloading Example File: Test.java importjava.io.*;classAddition{voidadd(intc,intd){System.out.println("The first ans is: "+(c+d));}voidadd(doublec,doubled){System.out.println("The second ans is: "+(c+d));}}publicclassTest{publicstaticvoidmain(String[]args){Addition obj=...
方法是一段普通的代码片段,并且这段代码可以完成某个特定的功能,而且可以被重复的调用/使用; java中的方法又叫做method,只要是可以独立出来的功能,我们都可以定义为单独的一个方法来完成,如果以后需要使用此功能时直接调用这个方法就行了; 不要把所有的代码都扔到main方法当中,这样会导致程序的“复用性”很差; 二...
In this tutorial, we will learn about method overriding in Java with the help of examples. If the same method defined in both the superclass class and the subclass class, then the method of the subclass class overrides the method of the superclass. This
