Create an application that will pass username and password on the next screen, using Java in Android Studio.

 Java Code:-

MainActivity.java

public class MainActivity extends AppCompatActivity {
    EditText username;
    EditText password;
    Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        username=findViewById(R.id.editusername);
        password=findViewById(R.id.editpassword);
        btn=findViewById(R.id.loginbutton);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(username.getText().toString().equals("tushar") && password.getText().toString().equals("password")){
                    Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
                    intent.putExtra("user", username.getText().toString());
                    intent.putExtra("pass", password.getText().toString());
                    startActivity(intent);
                }
            }
        });
    }
}

SecondActivity:-

public class SecondActivity extends AppCompatActivity {
    TextView user, pass;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        user=findViewById(R.id.second_user);
        pass=findViewById(R.id.second_pass);

        Bundle extra = getIntent().getExtras();
        String user1= extra.getString("user");
        String pass2= extra.getString("pass");
        user.setText(user1);
        pass.setText(pass2);
    }
}
