这样,其他类可以直接通过DateHelper类调用这两个方法,而无需重复编写这些功能。 如何使用helper类 下面是一个示例,演示如何使用上面创建的DateHelper类: publicclassMain{publicstaticvoidmain(String[]args){StringcurrentDate=DateHelper.getCurrentDate();StringcurrentTime=DateHelper.getCurrentTime();System.out.println(...
├──Helper.class └──Main.class 在上述场景中,multirelease.jar 可以在 Java 9 中使用, 不过 Helper 这个类使用的不是顶层的 multirelease.Helper 这个 class, 而是处在“META-INF/versions/9”下面的这个。这是特别为 Java 9 准备的 class 版本,可以运用 Java 9 所提供的特性和库。同时,在早期的 Jav...

此外,如果有许多helper函数只在扩展X的类中使用,但每个类中需要有一个稍微不同的实现呢? 下面是一个例子: public abstract class X { public abstract void doStuff(); int helperFunction(int a, int b) { return a + b; } abstract void secondHelperFunction(int x); ...
