KeyListener in JAVA

I will be setting up a program that uses keyListener. But for whatever reason it doesn’t perform. When I complie that i get one particular error: PythagoreanTriple. coffee 123: 1 missing method body, as well as declare abstract open public void keyReleased(KeyEvent e); Code: open public void keyPressed(KeyEvent e) int keycode = age. getKeyCode(); if(keycode == KeyEvent. VK_TAB) displayN. requestFocus(); open public void keyTyped(KeyEvent e) open public void keyReleased(KeyEvent e); displayN. requestFocus(); I don’t know why. Theoretically it should work. Might anyone help me Thanks! The problem is that you then have a semicolon (; ) immediately following keyReleased method announcement. The compiler thinks you aren’t creating a body, and declaring method and not using a body, which is only allowed with abstract methods. This is how your computer code should look: Code: open public void keyPressed(KeyEvent e) int keycode = age. getKeyCode(); if(keycode == KeyEvent. VK_TAB) displayN. requestFocus(); open public void keyTyped(KeyEvent e) open public void keyReleased(KeyEvent e) displayN. requestFocus(); Try it and determine if it works! WHOA. I am now wondering how POST looked over which. It was at school, so I got probably only half paying attention, but two some people missed it far too. Thanks!
