outputstreamwriter实现写入字符串

TestTransform1.java的源代码如下：
[code lang=”java”]
package com.daozhao.io;

import java.io.*;

public class TestTransform1 {
public static void main(String[] args){
try{
OutputStreamWriter osw =new OutputStreamWriter(new FileOutputStream("e:\\4.txt"));
osw.write("microsoftapplesunhp");
System.out.println(osw.getEncoding());
osw.close();

osw=new OutputStreamWriter(new FileOutputStream("e:\\4.txt",true),"ISO8859_1");
osw.write("helloworld");
System.out.println(osw.getEncoding());
osw.close();
} catch(IOException e){
System.out.println("未知错误");
System.exit(-1);
}
}
}
