Java读写记事本文件

Java中我们也会考虑读写记事本,文件读取如下:

public static void main(String[] args) {
try {
String path="d:\\abc.txt";//定义文件路径名称
//文件输入流
FileInputStream fs= new FileInputStream(path);
//内存输入流
InputStreamReader is=new InputStreamReader(fs);
BufferedReader br=new BufferedReader(is);
String line=br.readLine();
while(line!=null){
System.out.println(line);
line=br.readLine();
} //释放资源
br.close();
is.close();
fs.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

文件写入如下:

public static void main(String[] args) {
try {
String path="d:\\duanjt.txt";
String str= System.getProperty("line.separator");//换行符
String reout="duanjt"+str+"*"+str+"第三行";
FileOutputStream fos=new FileOutputStream(path);
fos.write(reout.getBytes());
fos.close();
System.out.println("文件写入成功"); } catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }

多的就不说了,代码比较简单,清晰明了
