Apps My program runs...but it doesn't work.

Essentially, my program has two EditTexts, a Button, and a TextView. You input a number/string into the EditText, and an output is supposed to be shown in the TextView. However, all i get is a 'There is no Department'. How do i fix this?

You can't use == to compare the contents of strings, it just checks to see if both pointers reference the same object. Use the String.equals() method instead. For example:

if (name.equals("Electronics"))

Also when you are testing for the department you could use a switch statement rather than the long sequence of if.. else's.

So, i've tried that. And my project crashed after i tested it on one to see if it would work. Progress?

And i haven't used a switch statement due to time constraints and it giving me an "Cannot convert from int to String" error.

What is the logcat output when it crashes?

You can only use a switch to compare against integers so you would have to keep the if...else statements in the name case.

Also, I assume you realise that you are calling setText() twice on the same TextView. The first text you set it to will be lost when you call setText() the second time.

That's just the bottom two entries of the stack, it doesn't tell you anything much. There should be a load of lines before that which will actually tell you what caused the problem.

That's all it gave me. I also changed the entire top part of it to a switch statement. I'd link you to it, but Pastebin is down.
The console gives me this on top of that.
