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;

}

}
