Hi Everybody, I was wondering if someone could help me figure out what is wrong with this part of my program. My program is a fraction calculator, and I'm wondering if the code I have is ok and if it will display correctly. Thanks much!!
Also should I add a button that says submit answer? and if so how would I integrate it.

public static void main(String[] args)
 {
  new MyNew();
 }
 
 MyNew()
 {
  //create panel
  JPanel mainFramePanel= new JPanel(new FlowLayout());
  //add action listener to buttons
  startButton.addActionListener(this);
  instructionsButton.addActionListener(this);
  backButton.addActionListener(this);
  //Adding names to JPanel
  mainFramePanel.add(startButton);
  mainFramePanel.add(instructionsButton);
  mainFramePanel.add(backButton);
  
  //Setting size to JPanel
  mainFrame.setContentPane(mainFramePanel);
  mainFrame.setSize(500,500);
  mainFrame.setVisible(true);
  
  // instructions frame
  JPanel instructionsFramePanel= new JPanel(new BorderLayout());
  JPanel sPane = new JPanel (new FlowLayout());
  
  instructionsReturnButton.addActionListener(this);
  
  instructionsFramePanel.add(instructionsReturnButton,BorderLayout.SOUTH);
  instructionsFramePanel.add(instructionsText,BorderLayout.CENTER);
  instructionsText.setLineWrap(true);
  instructionsText.setEditable(false);
  instructionsText.setWrapStyleWord(true);
  instructionsText.setText("gdjklhgoshgjkdhjkdhgkjdh");
  // setContent Pane and Size 
  instructionsFramePanel.add(sPane,BorderLayout.CENTER);
     instructionsFrame.setContentPane(instructionsFramePanel);
  instructionsFrame.setSize(500,500);
  instructionsFrame.setVisible(false);
  //numeratorOne=Integer.parseInt(inputA.getText())
  //calculator
  class MyNew implements ActionListener
{
 JButton answerButton= new JButton("Answer");
 JButton additionButton= new JButton("+");
 JButton subractionButton=new JButton("-");
 JButton multiplicationButton=new JButton("*");

 //Frames

  calculatorFramePanel.add(subtractionButton);
  calculatorFramePanel.add(multiplicationButton);
  calculatorFramePanel.add(divisionButton);
  calculatorFramePanel.add(answerButton);
  calculatorFramePanel.add(calculatorReturnButton);
 
  //Add Labelled input fields to display
  JPanel inFieldPane=newJPanel();
  inFieldPane.setLayout(new GridLayout(2,2));
  inFieldPane.add(newJLabel("First Numerator"));
  inFieldPane.add(firstNumerator);
  inFieldPane.add(newJLabel("First Denominator"));

  outFieldPane.add(answerResult);
  pane.add(outfieldPane,BorderLayout.SOUTH);
  //Display final product

  }

No, it's not correct. You need to re-examine the basics of class structure. You don't even have the class, constructor, and main method defined correctly.

This is just cobbled together pieces of UI creation code with no methods to actually do any computations. Even if it did compile it wouldn't do anything.
