具体如下：
连连看的小源码
package Lianliankan;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class lianliankan implements ActionListener
{
JFrame mainFrame; //主面板
Container thisContainer;
JPanel centerPanel,southPanel,northPanel; //子面板
JButton exitButton,resetButton,newlyButton; //退出,重列,重新开始按钮
JLabel fractionLable=new JLabel("0"); //分数标签
JButton firstButton,secondButton; //
static boolean pressInformation=false; //判断是否有按钮被选中
int x0=0,y0=0,x=0,y=0,fristMsg=0,secondMsg=0,validateLV; //游戏按钮的位置坐标
int i,j,k,n;//消除方法控制
代码（code）是程序员用开发工具所支持的语言写出来的源文件,是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系.
虽然用于表示 A 到 Z 拉丁字母表字符的位模式在所有的代码页中都相同,但用于表示重音字符（如"é"和"á"）的位模式在不同的代码页中却不同.如果在运行不同代码页的计算机间交换数据,必须将所有字符数据由发送计算机的代码页转换为接收计算机的代码页.如果源数据中的扩展字符在接收计算机的代码页中未定义,那么数据将丢失.

说明
不知道是否理解对了你的意思,大概写了一下：
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.StringReader;
import java.io.StringWriter;
public class FileReadAndWrite {
File file = new File("E:/workspace/FileIOTest/src/a.txt");
str = str.replace('d', 'f');
System.out.println("处理完毕");
* 文本文件转换为指定编码的字符串
* @param file
* 文本文件
* @param encoding
* 编码类型
* @return 转换后的字符串
* @throws IOException
InputStreamReader reader = null;
StringWriter writer = new StringWriter();
try {
if (encoding == null || "".equals(encoding.trim())) {
reader = new InputStreamReader(new FileInputStream(file),
encoding);
} else {
reader = new InputStreamReader(new FileInputStream(file));
// 将输入流写入输出流
char[] buffer = new char[DEFAULT_BUFFER_SIZE];
int n = 0;
while (-1 != (n = reader.read(buffer))) {
writer.write(buffer, 0, n);
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
if (reader != null)
reader.close();
} catch (IOException e) {
// 返回转换结果
if (writer != null)
return writer.toString();
else
* 将字符串写入指定文件(当指定的父路径中文件夹不存在时,会最大限度去创建,以保证保存成功！)
* @param res
* 原字符串
* @param filePath
* 文件路径
* @return 成功标记
boolean flag = true;
BufferedReader bufferedReader = null;
BufferedWriter bufferedWriter = null;
File distFile = new File(filePath);
if (!distFile.getParentFile().exists())
distFile.getParentFile().mkdirs();
bufferedReader = new BufferedReader(new StringReader(res));
bufferedWriter = new BufferedWriter(new FileWriter(distFile));
int len;
while ((len = bufferedReader.read(buf)) != -1) {
bufferedWriter.write(buf, 0, len);
bufferedWriter.flush();
bufferedReader.close();
bufferedWriter.close();
flag = false;
return flag;
if (bufferedReader != null) {
最简单的java代码肯定就是这个了,如下：
public class MyFirstApp
public static void main(String[] args)
System.out.print("Hello world");
