我写了个用集合存储的，你看看，能否帮上你
java.util.ListString list = new ArrayListString();
list.add("qq=123");//存储的时候用（用户名=密码）的形式
list.add("ww=456");
String username = "qq";
String password = "123";
for (int i = 0; i list.size(); i++) {
String num = username +"="+password;
if(num.equals(list.get(i))){
System.out.println("登录成功");
break;
}
}
你要先学会截图哦,你发的看不清楚,重新写了一个你参考参考!
