Question

I’m attempting to use IF THEN to add to and from integers in code:

 one.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            subtotal = 1;
            if (variable1==1) (counter + 1)

            else if (variable1==2) then (counter + 1);
            display.setText("Your total is" + counter);
        }
    });

But i get errors in my formatting i think.. =/

Many Thanks!

You should use curly brackets {}.
Also, saying counter + 1 doesn’t make much sense. I’m sure you mean counter += 1, which can be written as counter++, because you’re only adding one.

if (variable1==1) {
    counter++;
} else if (variable1==2) {
    counter++;
}

Also, since the body of the ifs are the same, you can have both expressions in the same if.

if (variable1==1 || variable1==2) {
    counter++;
}
