I can't work out what a lot of your code is trying to do, but here's
something based on what I *think* I can see.

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
class Abc extends JFrame implements ActionListener
{
  JLabel label1 = new JLabel();
  String[] text = {"Please Enter The Amount Inserted","Please Insert Your Cashcard",
                   "","Please Enter Your PIN"};
  JButton[] def = { new JButton("Cash"),new JButton("Cash Card"),new JButton(""),new JButton("Submit")};
  public Abc()
  {
    super("IT1290 Payment System");
    setDefaultLookAndFeelDecorated(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setSize(500,600);
    setLocation(200,100);
    Container contentPane = getContentPane();
    contentPane.setLayout(new GridLayout(5,1));
    for(int i = 0; i < def.length; i++)
    {
      def[i].addActionListener(this);
      contentPane.add(def[i]);
    }
    contentPane.add(label1);
  }
  public void actionPerformed(ActionEvent e)
  {
    for(int x = 0; x < def.length; x++)
    {
      if(e.getSource() == def[x])
      {
        label1.setText(text[x]);
        break;
      }
    }
  }
  public static void main(String[] args) {new Abc().setVisible(true);}
}

Hi "Seventh Theory" I am no the bartender in this forum, but, ouch, you are killing me.
First I'd like to welcome you to Javaranch. Please feel free to ask all your Java questions here, we really like helping everyone out, and we are really very friendly here.
And here is my "but", I understand being new, mistakes can happen, and don't think I am mad, casue I am not, but you seem to have broken almost all the rules. I know you said you will change your name, so here is the link.
1. First, we will start out with the JavaRanch Naming Policy.
You can change it
here.
2. The title of your thread should be more meaningful towards what you are going to actually post. please help is just very very vague.
3. Under the "Add Reply" button you will find many helpful buttons that can format your post to be more readable. For instance the button titled "CODE" can create tags that when wrapped around actual code will have the code retain all its formatting, including most importantly, your indentation. This makes is readable, and therefore easier for the reader to help you solve your problem.
