有什么其他要问的，你可以百度hi我！
包的英文是什么
包的英文读package。
在Java中，包主要有以下用途：
-包允许将类组合成较小的单元
-有助于避免命名冲突
-包允许在更广的范围内保护类、数据和方法
包可以是类、接口和子包的集合
创建包
package mypackage;
必须是.java文件中的第一句话
访问 Java包成员
mypackage.My_Class
导入包
import package_name.*;
导入子包
import package_name.package_sub.*；
编译
javac–d<目录名> xx.java
运行
java包名.类名
如何使用自定义的包：
自己定义一个.java文件，创建一个包
例如：该文件是Test.java文件，创建的包是com.accp
那么，编译该文件后生成的Test.class的包路径是
com.accp.Test.class
将该文件加入classpath中
a.如果将.class文件导入classpath中，那么应该在classpath导入包含该.class文件所在最上级包的目录
例如：Test.class文件最上级包目录是com文件夹，com文件夹在c:\，所以应该加入c:\
b.如果将.jar文件加入classpath中，就应该在classpath中导入该.jar文件的详细路径。
