How to fix the message passing error between the activities

Question

I had created a simple message passing application in android studio to include this code into my Project work.But I was not able to switch the activity by passing a string into another activity.please help me out to find the problem.

When the button is triggered the application got ended itself instead of switching the activity.I had tried many ways to figure it out.

First Activity(MainActivity)

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn;
        EditText text;
        btn = (Button)findViewById(R.id.button);
        text = (EditText)findViewById(R.id.editText);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String mess = text.getText().toString();
                Intent i= new Intent(MainActivity.this,Main2Activity.class);
                intent.putExtra("EXTRA",mess);
                startActivity(i);
            }
        });
    }
}

Second Activity(Main2Activity)

public class Main2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

       EditText editText  = (EditText)findViewById(R.id.editText2);
       editText.setText(getIntent().getStringExtra("EXTRA"));
    }
}

The expected output was to exchange the data from one activity to another, but now the application gets stopped.
