package myapp;publicclassMyClass{// 类的实现...} 上述代码中,MyClass类被声明为属于myapp的包。在其他的代码中使用该类时,需要使用完整的包名来引用它。例如: importmyapp.MyClass;publicclassAnotherClass{MyClassmyClass =newMyClass(); } packge 在Java中,包(Package)是用于组织和管理类和接口的一种机制。
然后,在另一个类中使用这两个Person类: importcom.example.PersonasExamplePerson;importcom.another.PersonasAnotherPerson;publicclassMain{publicstaticvoidmain(String[]args){ExamplePersonexamplePerson=newExamplePerson("Alice");AnotherPersonanotherPerson=newAnotherPerson("Bob");System.out.println("Example person'...
importcom.example.ClassA;importcom.anotherexample.ClassA; 1. 2. 上述代码表示导入了两个同名的类ClassA,分别来自com.example和com.anotherexample两个包。通过这样的导入,我们可以在代码中区分它们,而不会出现命名冲突的情况。 以上就是关于Java中import关键字的详细介绍。通过使用import,我们可以提高开发效率,使代...
