java中在控制台循环输入密码的问题

先指定一个密码,然后从控制台输入一个密码,验证密码的正确性,错误的话重新输入直到输入密码符合指定密码为止,举一个具体的例子看看

Answer 1

public class Test {

public static void main(String[] args) {
String password = "password";
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
try {
String read = null;
do{
read = br.readLine();
}while(!password.equals(read));
} catch (IOException e) {
e.printStackTrace();
}
}

}

Answer 2

写个循环
while(iss){
if(pwd==123){
iss=false;

}

}

密码正确进if 下次循环会跳出

Answer 3

String target = "your string";
Scanner scanner = new Scanner(System.in);
String temp = scanner.next();
while(!temp.equals(s)){
temp = scanner.next();
}
