EditText.getText().toString() error [duplicate]

This question already has an answer here:

there is this code I'm working with, and the log shows that there is an error that terminates the app like

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.text.Editable android.widget.EditText.getText()' on a null object reference
at com.example.amuna.project1.addWord.confirmBtnClicked(addWord.java:25)


and the code is

import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class addWord extends AppCompatActivity
EditText wordEdit, defEdit;
Button confirmButton;
@Override
public void onCreate(Bundle savedInstanceState)
wordEdit=(EditText)findViewById(R.id.wordAdd);
defEdit=(EditText)findViewById(R.id.defAdd);
confirmButton=findViewById(R.id.confirmBtn);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_word);

public void confirmBtnClicked(View v)
SharedPreferences pref = getSharedPreferences("pref", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
String newWord = wordEdit.getText().toString();
String newDef = defEdit.getText().toString();
editor.putString("word", newWord);
editor.putString("def", newDef);
editor.commit();





please help! It's String newWord = wordEdit.getText().toString(); that has an error, and please notice me if I have anything more wrong. Thanks!

You should set the content view, by calling setContentView(R.layout.activity_add_word);, before wordEdit=(EditText)findViewById(R.id.wordAdd);. Change the code as follows:

setContentView(R.layout.activity_add_word);

wordEdit=(EditText)findViewById(R.id.wordAdd);

@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_word);
wordEdit=(EditText)findViewById(R.id.wordAdd);
defEdit=(EditText)findViewById(R.id.defAdd);
confirmButton=findViewById(R.id.confirmBtn);
