fileexe.java

Java语言程序设计-源代码（第三部分）和课程相对应的提供了一些用于学习理解的代码设计

import java.io.*;
class FileExe{
	public static void main(String args[]){
	int count;
	byte b[]=new byte[1024];
	FileInputStream fis;
	FileOutputStream fos;
	try{
		fis=new FileInputStream(args[0]);
		}
	catch(FileNotFoundException e){
		System.out.println("InputFile is not found!");
		return;
	}
	try{
		fos=new FileOutputStream(args[1]);
		}
	catch(FileNotFoundException e){
		System.out.println("OutputFile is not found!");
		return;
	  }
	catch(ArrayIndexOutOfBoundsException e){
		System.out.println();
		return;}
	try{
		while((count=fis.read(b,0,1024))!=-1)
		{fos.write(b,0,count);}
		}
	catch(IOException e){
		System.out.println("Error:"+e);
		return;
