Java, compare keyboard input values with file.txt values

Question

SOLVED!

I have a kind of homework, where I have a file where I have username and password like this:

user1 password1

user2 password2

user3 password3

I need to use FileInputStream class, and I also need to keyboard input username and password and check if it already exists (every username must match password, on line). I decided to use Map for that but .... if you take a look into my while loop, I tried to split into key and value. I also created map2 who stores keyboard input, and map who stores split key and value.

My trouble is here: if I input username: user1, password: password1, that condition if(map.equals(map2)) will return true. But if I write for username: user2 and password: password2, "if" will return false, even if user2 and password2 already exists in my file.

Tip: I can't override equals() and hashCode() because I don't have any class here, out of my main class.

public class ex_2 
{
public static void main(String args[]) throws IOException
{
    InputStreamReader reader = new InputStreamReader(System.in);
    BufferedReader br = new BufferedReader(reader);
    System.out.print("username: ");
    String user = br.readLine();
    System.out.print("password : ");
    String pass = br.readLine();

    FileInputStream input= new FileInputStream("file.txt");
    BufferedReader read= new BufferedReader(new InputStreamReader(input));


    Map<String, String> map = new HashMap<String,String>();
    Map<String, String> map2 = new HashMap<String,String>();
    map2.put(user, pass);
    System.out.println(map2);
     String line;
     while((line = read.readLine()) !=null)
     {
        String[] split = line.split("\t\t");
        map.put(split[0], split[1]);

        if(map.equals(map2))
        {
            System.out.println("True");
        }
        else
        {
            System.out.println("False");
        }
     }
     System.out.println(map);
     read.close();

code for @SMA

     String line;
     while((line = read.readLine()) !=null)
     {
            String[] split = line.split("\t\t");
            map.put(split[0], split[1]);
            String passwordInFile = map.get(user);
             if (passwordInFile != null && passwordInFile.equals(pass)) 
                 System.out.println("True");
             else 
                 System.out.println("False");
     }

You shouldn't be comparing two maps. Instead compare for values in the map once you have all the values that are stored in a file like:

 String passwordInFile = map.get(user)
 if (passwordInFile != null && passwordInFile.equals(pass)) {
     System.out.println("True");
 } else {
     System.out.println("False");
 }
