Question

Can you help me to link two frames in Java Swing and then if you click "Proceed button" it will link to the Second Frame...Thank you :)

First frame code:

//First

import javax.swing.*;
import java.awt.event.*;
import java.io.*;

public class Sample extends JFrame implements ActionListener {
JMenuBar mb;
JMenu file;
JMenuItem open;
JTextArea ta;
JButton proceed= new JButton("Proceed");
Sample() {
open = new JMenuItem("Open File");
open.addActionListener(this);
file = new JMenu("File");
file.add(open);
mb = new JMenuBar();
mb.setBounds(0, 0, 400, 20);
mb.add(file);
ta = new JTextArea(400, 400);
ta.setBounds(0, 20, 400, 400);
proceed.setBounds(200, 450, 100, 40);
proceed.addActionListener(new ActionListener() {
  
@Override
public void actionPerformed(ActionEvent a) {
secondbox s = new secondbox();
}
});
add(proceed);
add(mb);
add(ta);

}

public void actionPerformed(ActionEvent e) {
if (e.getSource() == open) {
JFileChooser fc = new JFileChooser();
int i = fc.showOpenDialog(this);
if (i == JFileChooser.APPROVE_OPTION) {
File f = fc.getSelectedFile();
String filepath = f.getPath();
try {
BufferedReader br = new BufferedReader(new FileReader(filepath));
String s1 = "", s2 = "";
while ((s1 = br.readLine()) != null) {
s2 += s1 + "\n";
}
ta.setText(s2);
br.close();
} catch (Exception ex) {
ex.printStackTrace();
}

}
}
}

public static void main(String[] args) {
First om = new First();
om.setSize(600,600);
om.setLayout(null);
om.setVisible(true);
om.setDefaultCloseOperation(EXIT_ON_CLOSE);
}
}

Second Frame Code:

import javax.swing.*;
import java.awt.event.*;
class Second implements ActionListener{
JLabel l1,l2;
JTextArea area;
JButton b,b1,b2;
JFrame f;

Second() {
f= new JFrame();
l1=new JLabel();
l1.setBounds(120,25,120,50);
l2=new JLabel();
l2.setBounds(290,25,100,50);
area=new JTextArea();
area.setBounds(120,90,280,200);
b=new JButton("Count Char");
b.setBounds(280,300,120,30);
b1=new JButton("Clear"); //added feature
b1.setBounds(120,300,120,30);
b.addActionListener(this);
b.addActionListener((e -> {
String text=area.getText();
String words[]=text.split("\\s");
l1.setText("Words: "+words.length);
int count=0;
for (int i=0;i<text.length();i++){
if(text.charAt(i)!=' ')
count++;
}
l2.setText("Char: "+count);
b.setVisible(false);
b1.setVisible(false);
b2=new JButton("Proceed");
b2.setBounds(280,300,120,30);
f.add(b2);
}));
b1.addActionListener((e -> {
area.setText("");
}));
f.add(l1);f.add(l2);f.add(area);f.add(b);f.add(b1);
f.setSize(500,500);
f.setLayout(null);
f.setVisible(true);
}
  
public void actionPerformed(ActionEvent e){
String text=area.getText();
String words[]=text.split("\\s");
l1.setText("No.of Words: "+words.length);
int count=0;
for (int i=0;i<text.length();i++){
if(text.charAt(i)!=' ')
count++;
}
l2.setText("No.of Char: "+count);
}
public static void main(String[] args) {
new Second();   
}
}

Answer 1

if you have any Query comment Down below

SIMPLY copy the code in two classes and run

SS:

- O X - 0 X Clear Clear C ount Char Proceed

Code:

Class#1

import javax.swing.*;
import java.awt.event.*;
import java.io.*;

public class Sample extends JFrame implements ActionListener {
JMenuBar mb;
JMenu file;
JMenuItem open;
JTextArea ta;
JButton proceed= new JButton("Proceed");
Sample() {
open = new JMenuItem("Open File");
open.addActionListener(this);
file = new JMenu("File");
file.add(open);
mb = new JMenuBar();
mb.setBounds(0, 0, 400, 20);
mb.add(file);
ta = new JTextArea(400, 400);
ta.setBounds(0, 20, 400, 400);
proceed.setBounds(200, 450, 100, 40);
proceed.addActionListener(new ActionListener() {
  
@Override
public void actionPerformed(ActionEvent a) {
Second s = new Second();
}
});
add(proceed);
add(mb);
add(ta);

}

public void actionPerformed(ActionEvent e) {
if (e.getSource() == open) {
JFileChooser fc = new JFileChooser();
int i = fc.showOpenDialog(this);
if (i == JFileChooser.APPROVE_OPTION) {
File f = fc.getSelectedFile();
String filepath = f.getPath();
try {
BufferedReader br = new BufferedReader(new FileReader(filepath));
String s1 = "", s2 = "";
while ((s1 = br.readLine()) != null) {
s2 += s1 + "\n";
}
ta.setText(s2);
br.close();
} catch (Exception ex) {
ex.printStackTrace();
}

}
}
}

public static void main(String[] args) {
Sample om = new Sample();
om.setSize(600,600);
om.setLayout(null);
om.setVisible(true);
om.setDefaultCloseOperation(EXIT_ON_CLOSE);
}
}
Class #2..

import javax.swing.*;
import java.awt.event.*;
public class Second implements ActionListener{
JLabel l1,l2;
JTextArea area;
JButton b,b1,b2;
JFrame f;

Second() {
f= new JFrame();
l1=new JLabel();
l1.setBounds(120,25,120,50);
l2=new JLabel();
l2.setBounds(290,25,100,50);
area=new JTextArea();
area.setBounds(120,90,280,200);
b=new JButton("Count Char");
b.setBounds(280,300,120,30);
b1=new JButton("Clear"); //added feature
b1.setBounds(120,300,120,30);
b.addActionListener(this);
b.addActionListener((e -> {
String text=area.getText();
String words[]=text.split("\\s");
l1.setText("Words: "+words.length);
int count=0;
for (int i=0;i<text.length();i++){
if(text.charAt(i)!=' ')
count++;
}
l2.setText("Char: "+count);
b.setVisible(false);
b1.setVisible(false);
b2=new JButton("Proceed");
b2.setBounds(280,300,120,30);
f.add(b2);
}));
b1.addActionListener((e -> {
area.setText("");
}));
f.add(l1);f.add(l2);f.add(area);f.add(b);f.add(b1);
f.setSize(500,500);
f.setLayout(null);
f.setVisible(true);
}
  
public void actionPerformed(ActionEvent e){

count++;
}
l2.setText("No.of Char: "+count);
}
public static void main(String[] args) {
new Second();   
}
