Suppose you are trying to prepare a Calculator using java programming language and also you are trying to prepare your calculator using JTextField (javax.swing.JTextField).

Here I have given a little example how to use TextField (JTextField) of java in JFrame.

Using the following code you will be able to learn how to put or use or show 🙂 TextField (JTextField) in java  and how to position the TextField in JFrame.


 Here is the Code Example:

import javax.swing.*;

import java.awt.Dimension;

import java.awt.Toolkit;

public class Calc extends JFrame


   JTextField ques, answer;

   private Toolkit toolkit;

        public Calc()


                        JPanel panel =new JPanel();



                        // UIManager.LookAndFeelInfo laf[]=UIManager.getInstalledLookAndFeels();


                setTitle(“Easy Calculator”);



                Dimension size=toolkit.getScreenSize();

                 setLocation(size.width/2-getWidth()/2, size.height/2-getHeight()/2);

                 ques=new JTextField();

                 answer=new JTextField();

        JButton calculate=new JButton(“Calculate”);


        ques.setBounds(10,10,220,30);     // Positioning of TextField(JTextField)

        answer.setBounds(10,100,220,30); //Positioning  of TextField(JTextField)


        panel.add(ques );    // Adding TextField(JTextField) in JPanel

        panel.add(answer );  // Adding TextField(JTextField) in JPanel


          public static void main(String args[])


              Calc  cal=new Calc();
