IO编程__字符流__输入、输出

一、代码如下

package www.tainiu.wenjian;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.lang.Character.UnicodeBlock;

public class ae__FileString__V1 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		FileReader fr= null;
		FileWriter fw= null;
		
		try {
			fr= new FileReader("d:\Test.txt");
			fw= new FileWriter("e:\Test.txt");
			String test= "jst";
			String test2= "jst讲解";
			String s= null;
			
			char[] chars= new char[1024];
			int n= 0;
			while((n=fr.read(chars)) != -1) {
//				s= new String(chars);
//				String newString= new String(s.getBytes(), "gbk");
//				String utf8= new String(newString.getBytes("UTF-8")); 
//				String gbk1= new String(utf8.getBytes("GBK")); 
				//String newString_V2= new String(unicode.);
//				System.out.println(gbk1);
				//fw.write(chars, 0, n);
				fw.write(chars);
//				fw.write(gbk1);
			
			}
			//fw.write(chars);
			//fw.write(test);
			//fw.write(test2);
			
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			try {fr.close();fw.close();} catch (Exception e1) {e1.printStackTrace();}
		}

	}
