Question

I want to compare two sets of digits. The first I will generate as a random in code. The second will be entered into an EditText.

I wish to compare the two numbers and see if they match.

Random number:

public static int random() {
   if (randomNumberGenerator == null)
      initRNG();

   return randomNumberGenerator.nextInt();
}

private static Random randomNumberGenerator;
private static synchronized void initRNG() {
   if (randomNumberGenerator == null)
      randomNumberGenerator = new Random();
}

Showing randomly selected number

display = (TextView) findViewById (R.id.textView1);
display.setText ("Random Number:" + random ());

How can I compare the two numbers?

Answer 1

Just make a subtraction between both numbers and if the result is 0, both numbers match.

EDIT: Subtraction was just a way to show that both were numbers. Obviously it makes more sense to compare both numbers directly rather than subtracting and comparing then.
