求此程序编译结果
小弟不懂JAVA，也没用环境，程序没问题，
求哪位老大帮忙给运行一下
我想知道通过解密之后的 password的值是多少
主程序
String password="3v3TaGU4x%2FkCGu0YufDbJ9cRhsAlhM3KXt789hPC3qUiuhI38yGoD6hHSeh6R34TGwnjYI6EApKXzDlj6%2BDvQQ%3D%3D";
DesSecret desSecret = new DesSecret();
String key = "Sx@!168#$%@As56";
password = desSecret.get3DESDecrypt(password, key);
