hello. i am trying to make a text editor. i can't figure out how to get the file that i select in the JFileChooser to
show in the JTextArea. and I also can't figure out how to get the text from the JTextArea to save into a .txt file.

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

public class mainC implements ActionListener{
	public static void main(String[] agrs){
		new mainC();
	}
	
	final JFileChooser fc = new JFileChooser("c:\\");
	
	mainC(){
		JFrame frame=new JFrame();
		
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
		frame.setSize(screenSize.width - 4, screenSize.height - 30);
		frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
		frame.validate();
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		//******set JMenuBar
		JMenuBar menuBar=new JMenuBar();
		frame.setJMenuBar(menuBar);
		
		//******Add Menus
		JMenu file=new JMenu("File");
		menuBar.add(file);
		
		//******Add MenuItems
		
		//Open File
		JMenuItem open=new JMenuItem("Open File");
		open.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e){
			final int openVal = fc.showOpenDialog(fc);
			switch(openVal){
			case JFileChooser.APPROVE_OPTION:
				//Open was clicked
				
				JDialog currentFileF=new JDialog();
				currentFileF.setVisible(true);
				currentFileF.setSize(800,600);
				
				JTextArea textArea= new JTextArea();
			    JScrollPane pane = new JScrollPane(textArea, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
			    currentFileF.add(pane);
				
			case JFileChooser.CANCEL_OPTION:
				//Cancel was clicked
			case JFileChooser.ERROR_OPTION:
				//Error Occurred
			}
		}});
		
		//Save File
		JMenuItem save=new JMenuItem("Save File");
		save.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e){
			int saveVal=fc.showSaveDialog(fc);
			switch(saveVal){
			case JFileChooser.APPROVE_OPTION:
				//Open was clicked
			case JFileChooser.CANCEL_OPTION:
				//Cancel was clicked
			case JFileChooser.ERROR_OPTION:
				//Error Occurred
			}
		}});
		
		file.add(open);
		file.add(save);
		file.addSeparator();
	    
	}
	
	public void actionPerformed(ActionEvent arg0) {}
}

thank you!

you need to set the value of the text of the textarea, and you need to add the textarea to the panel.

I also suggest you to declare your textarea on class scope, that way you will be able to (re)set the value of the text in the textarea.
