Java Program to create following GUI | EasyCoding45

 In this tutorial we are going to learn how we can create following GUI using java.

Program :-

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

class B1 extends JFrame implements ItemListener

{

JLabel l1,l2,l3;

JCheckBox jc[]=new JCheckBox[3];

JComboBox jcs;

JComboBox jcf;

JPanel p4,p3,p1,p2;

JTextField t;

B1()

{

p1=new JPanel();

p2=new JPanel();

p3=new JPanel();

p4=new JPanel();

t=new JTextField(10);

l1=new JLabel("Font");

l2=new JLabel("Style");

l3=new JLabel("Size",JLabel.CENTER);

String[] fonts=new String[]{"Arial","Times New Roman","Courier New"};

String[] size=new String[]{"10","15","20","25"};

jcf=new JComboBox(fonts);

jcs=new JComboBox(size);

jcs.addItemListener(this);

jcf.addItemListener(this);

p1.add(l1);

p1.add(jcf);

p2.add(l2);

p3.add(l3);

p3.add(jcs);

l1.setBounds(100,100,25,25);

l2.setBounds(210,100,25,25);

p4.add(t);

jc[0]=new JCheckBox("Bold");

jc[1]=new JCheckBox("Italic");

jc[2]=new JCheckBox("UnderLine");

for(int i=0;i<3;i++)

{

p2.add(jc[i]);

jc[i].addItemListener(this);

}

add(p1);

add(p2);

add(p3);

add(p4);

setLayout(new GridLayout(2,2));

setSize(300,300);

setVisible(true);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public void itemStateChanged(ItemEvent ie)

{

String fnt=(String)jcf.getSelectedItem();

String size1=(String)jcs.getSelectedItem();

int size=Integer.parseInt(size1);

String cb="";

for(int i=0;i<3;i++)

{

if(jc[i].isSelected())

{

cb=jc[i].getText();

}

}

if(cb.equals("Bold"))

{

t.setFont(new Font(fnt,Font.BOLD,size));

}

else if(cb.equals("Italic"))

{

t.setFont(new Font(fnt,Font.ITALIC,size));

}

else

t.setFont(new Font(fnt,Font.PLAIN,size));

}

public static void main(String ar[])

{

new B1();

}

}

Output :-
