Question

Why am I getting ” } ” error in switch statment below. I don’t see any syntax error.
I don’t get error on compiling the code. Eclipse is indicating error at the specified position below.

After putting } I get this error

- The static field KeyEvent.VK_XXXX should be accessed in a 
 static way
- case expressions must be constant expressions

switch(event.getKeyCode())
        {
        case event.VK_BACK_SLASH:
            backColor=but[27].getBackground();
            break;

        case event.VK_RIGHT:
            for(int i=0;i<but.length;i++)
            {
                if(" > ".equals(but[i].getText()))
                {
                    backColor=but[i].getBackground();
                    break;
                }
            }
            break; // error here
   }

When I press the key, I get the follwoing error

Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation problem: 
Syntax error, insert "}" to complete SwitchBlock

    at Keyboard$HandlerClass.keyPressed(Keyboard.java:242) // this is break statement

The only problem I could see in your code is the following (but it’s not a compiletime/runtime error), which most probably would end up as a bug:

but[i].getText() == " > " //this is called object identity check

That’s not the right way to compare strings. Use .equals method instead

" > ".equals(but[i].getText()) //this is object equality check

Update

The static field KeyEvent.VK_XXXX should be accessed in a static way

That means you should change event.VK_BACK_SLASH to KeyEvent.VK_BACK_SLASH, …
