Hey guys, complete newbie here!
Essentially, I'm creating a game where the player has to guess the randomly generated number. The Program compiles, however after I enter a number and click the button to enter the App crashes. Any help + general tips are welcome. Thank you!

Essentially, I'm creating a game where the player has to guess the randomly generated number. The Program compiles, however after I enter a number and click the button to enter the App crashes. Any help + general tips are welcome. Thank you!
main activity code:
Java:
package com.example.week_1_java;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
//elements we are intercating iwth
Guess game;
TextView textView; //INSTRUCTIONS
TextView textView2;
EditText edittext2; // TEXT FIELD FOR USER INPUT OF NUMBER GUESS
Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting the ui elements
textView = findViewById(R.id.textView);
textView2 = findViewById(R.id.textView2);
edittext2 = findViewById(R.id.editText2);
button1 = findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
game.setNewValue();
makeguess1();
}
});
}
public void makeguess1(){
//Get our Guess value from the edit text by getting the input text and
//casting the number from the string
String usertext = edittext2.getText().toString();
int result = Integer.parseInt(usertext);
//remove the text from the edit text so that the user knows that the guess has
//been input
edittext2.setText("");
//pass the guess to the Guess object and change the result text
//and button state based on the result
if (game.MakeGuess(result)) {
//user was correct so set the result text to the win condition
textView2.setText(R.string.correct);
//set the button state to try again so user can reset the game
} else {
//otherwise user was incorrect so set the result text
textView2.setText(R.string.incorrect);
}
}
}My Guess Class Code:
Java:
package com.example.week_1_java;
import java.util.Random;
public class Guess {
int valueToGuess;
Random randomguess = new Random();
int Range =15;
Guess()
{
setNewValue();
};
void setNewValue()
{
valueToGuess = 1+randomguess.nextInt(Range-1);
};
public boolean MakeGuess(int userToGuess)
{
boolean correct = false;
if(userToGuess == valueToGuess){
correct = true;
}
return correct;
};
}
