Help, Setting Key Code

[quafflepunch]

Sorry if this is in the wrong area, but I am new to the forum.
I am trying to have it so that when you click on a button, whatever you type next will appear on the button and be set as the keyCode for the corresponding place.

import java.awt.event.*;
import javax.swing.*;
public class OptionsForm extends JFrame implements MouseListener, KeyListener  {
  ImageIcon optionsScreen = new ImageIcon("J:\\this course\\assets\\art\\backgrounds\\OptionsMenu.JPG");
  static KeyEvent[] up=new KeyEvent[2];
  KeyEvent[] right=new KeyEvent[2];
  
  KeyEvent[] left=new KeyEvent[2];
  KeyEvent[] attack=new KeyEvent[2];
  KeyEvent[] crouch=new KeyEvent[2];
  JButton oneUp=new JButton("Up");
  JButton twoUp=new JButton("8");
  JButton oneRight=new JButton("Right");
  JButton twoRight=new JButton("6");
  JButton oneLeft=new JButton("Left");
  JButton twoLeft=new JButton("4");
  JButton oneAttack=new JButton("Space");
  JButton twoAttack=new JButton("0");
  JButton oneCrouch=new JButton("Down");
  JButton twoCrouch=new JButton("5");
  JButton audioBrowse=new JButton("Browse");
  JButton charBrowse=new JButton("Browse");
  MouseEvent clicked;
  
  
  JFileChooser charInput=new JFileChooser();
  JFileChooser audioInput;  
  public OptionsForm() {
    up[0].setKeyCode(KeyEvent.VK_UP); //this is my error line
    this.setFocusable(true);
    setBounds(100,50,600,300);
    setLayout(null);     
    this.setTitle("Options");
    optionsImage = new JLabel(optionsScreen,0);
    //constructs Form with layout and title
    optionsImage.setBounds(0,0,600,280);
    oneUp.setBounds(360,93,107,34);
    twoUp.setBounds(467,93,107,34);
    oneRight.setBounds(360,127,107,34);
    twoRight.setBounds(467,127,107,34);
    oneLeft.setBounds(360,161,107,34);

    oneCrouch.addMouseListener(this); oneCrouch.setFocusable(false);

    this.addKeyListener(this);
    //adds objects to form
    add(oneUp);
    add(twoUp);
    add(oneRight);
    add(twoRight);
    add(oneLeft);
    add(twoLeft);

      crouch[1]=kevt;
      twoCrouch.setText(Character.toString(kevt.getKeyChar()));}
    }
  }
  public void keyPressed(KeyEvent evt) {}
  public void keyReleased (KeyEvent ke) {}
  
  
  
    public javax.swing.JLabel optionsImage;
}

any help would be appreciated

You are using Swing, you can use Key Binding instead.
See this page How to Use Key Bindings (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
