Java——利用转换流将GBK格式文件以UTF-8输出

利用转换流将GBK格式文件以UTF-8输出
实现代码：

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;

public class HomeWork2 {
	public static void main(String[] args) throws IOException {
		GBKtoUTF("D:\\360MoveData\\Users\\xucc\\Desktop\\h.cpp", "D:\\\\360MoveData\\\\Users\\\\xucc\\\\Desktop\\\\h2.cpp");
	}
	public static void GBKtoUTF(String file1,String file2) throws IOException {
		//1.创建InputStreamReader对象，构造方法中传递字节输入流和指定的编码表名称GBK
		InputStreamReader isr = new InputStreamReader(new FileInputStream(file1),"GBK");
		//2.创建OutputTreamWrite对象，构造方法中传递字节输出流和指定的编码表名称UTF-8
		OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream(file2),"utf-8");
		int len = 0;
		while((len = isr.read()) != -1) {
			osw.write(len);
		}
		 //3.释放资源
		isr.close();
		osw.close();
	}
