如何在java中使用别人提供的jar包进行导入，编译，运行

package com.security;

import com.security.AESencrp;
/**
* 实现AES加密
* g882
* 2016-11-16
*/
public class Checker {
public static void main(String[] args) throws Exception {
// 创建加解密
AESencrp aes = new AESencrp();
// 要进行加密的密码
String password = "password^*(&( 09-8ADF";
// 进行加密后的字符串
String passwordEnc = aes.encrypt(password);
String passwordDec = aes.decrypt(passwordEnc);
System.out.println("原来的密码 : " + password);
System.out.println("加密后的密码 : " + passwordEnc);
System.out.println("解密后的原密码 : " + passwordDec);
}
}

javac -cp com/security/AESencrp.jar com/security/Checker.java

java  -cp .;com/security/AESencrp.jar com/security/Checker
