receive a string message from user input in android and parse to an int so can be stored in an array and compared with another array of integers

Question

I am having a problem with the above task in my android application. I am accepting user input from the EditText widget in the form of String. I accepting numbers from the user so I have to parse them to integers so they can be compared with another array of integers. I have the line:

String message = editText.getText().toString()

then to try and parse the String to an int I have the code line:

int userNumbers = Integer.parseInt(message).

However when I attempt to compare the array userArray with the array numbers I am getting the error that "Incompatible operand types String and Integer.

Can anyone see where my problem is or how I can solve it? Here's my code: Thanks in advance.

public class MainActivity extends Activity {
    public final static String EXTRA_MESSAGE = ".com.example.lotterychecker.MESSAGE";
    static boolean bonus = false;
    static boolean jackpot = false;
    static int lottCount = 0;
    Button check;
    Integer [] numbers;

Answer 1

You have this

Integer [] numbers; // numbers is an integer array

You have string array

String [] userArray = new String[SIZE]; // userArray is a string array

You compare like below

if (userArray[loop] == numbers[loopOther])

So you get the error Incompatible operand types String and Integer.

try

if (Integer.parseInt(userArray[loop]) == numbers[loopOther])

Enclosing the above with try catch block

String message = editText.getText().toString();
try{
    int userNumbers = Integer.parseInt(message); 
     //is this right? yes
    }
    catch (NumberFormatException e)
    {
        e.printStacktrace();


    }
