introduceframe.java

一个小的编译器,可以模仿类似c语言的语法。很适合初级java学习者

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


public class IntroduceFrame extends JFrame
{
	TextArea introduceArea;
	byte buffer[];
	int bufferLength;
	
	public IntroduceFrame()
	{
		buffer = new byte[100000];
		
		try
		{
			File file = new File("help","introduce.txt");
			if(!file.exists())
			{
				System.err.println("Introduce text is not existing");
			}
			FileInputStream fileInputStream = new FileInputStream(file);
			bufferLength=fileInputStream.read(buffer);
			fileInputStream.close();
			
		}
		catch(Exception e)
		{
			
		}
		String string = new String(buffer);
		
		introduceArea = new TextArea(string);
		introduceArea.setBackground(Color.LIGHT_GRAY);
		introduceArea.setEditable(false);
		
		
		setTitle("Introduce Text");
		setSize(500,450);
		getContentPane().add(introduceArea);
	//	pack();
		
		
		addWindowListener
		(
			new WindowAdapter()
			{
				public void windowClosing(WindowEvent we)
				{
					setVisible(false);
					
				}
			}
		);	
	}
