Java io 编程基础应用实现方法基础

import java.io.*;
public class TTTStream{
	public static void main(String[] args){
		int b = 0;
		FileInputStream in =null ;
		FileOutputStream out=null;
		try{
			in = new FileInputStream("D:\\java\\io\\TTTStream.java");
			out = new FileOutputStream("D:\\java\\io\\TestOutStream.java");
		
			while((b=in.read())!=-1){
				out.write(b);
				System.out.print((char)b);
				}
				in.close();
		    out.close();
			}	catch(IOException e1){System.out.println("file is error1");
				System.exit(-1);}
	System.out.println("文件已复制");
	     
		}
	}
