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();
getContentPane().add(panel);
panel.setLayout(null);
// UIManager.LookAndFeelInfo laf[]=UIManager.getInstalledLookAndFeels();
setSize(300,200);
setTitle(“Easy Calculator”);
setDefaultCloseOperation(EXIT_ON_CLOSE);
toolkit=getToolkit();
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”);
calculate.setBounds(75,50,90,30);
ques.setBounds(10,10,220,30); // Positioning of TextField(JTextField)
answer.setBounds(10,100,220,30); //Positioning of TextField(JTextField)
panel.add(calculate);
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();
cal.setVisible(true);
}
}
