Java se 流的相关问题
import java.io.*;

public class Transform{
public static void main(String[]args){
//InputStreamReader r=new InputStreamReader(new FileReader("D:/java/io/d.txt"));
try{
OutputStreamWriter o=new OutputStreamWriter(new FileOutputStream("D:/java/io/d.txt"));
o.write("种过萝卜");
System.out.println(o.getEncoding());
o.close();
o=new OutputStreamWriter(new FileOutputStream("D/java/io/d.txt",true),"jkk_jjj");
o.write("种过萝卜");
System.out.println(o.getEncoding());
o.close();
}catch(FileNotFoundException e){
System.out.println("文件找不着");
System.exit(-1);
}catch(IOException e){
System.out.println("文件读取错误");
System.exit(-1);
}
}
}

为什么o=new OutputStreamWriter(new FileOutputStream("D/java/io/d.txt",true),"jkk_jjj");没有输出“jkk_jjj”,直接跳到“文件找不着”，哪里出错了呢


------解决方案--------------------
三个问题:
1 需要有d:\java\io这样的目录结构。
2

Java code

o=new OutputStreamWriter(new FileOutputStream("D/java/io/d.txt",true),"jkk_jjj");
