Java中高級IO流的使用-Copy文件

主要一下面代碼實現

package com.file.ou;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;


public class TestCopy {
	public static void main(String[] args) {
		FileInputStream fis=null;
		FileOutputStream fos=null;
		BufferedInputStream bis=null;
		BufferedOutputStream bos=null;
		try {
//			可自定義/修改成方法
			fis=new FileInputStream("F:\\abc.txt");
			fos=new FileOutputStream("E:\\a.txt");
			bis=new BufferedInputStream(fis);
			bos=new BufferedOutputStream(fos);
			int temp=0;
			while((temp=bis.read())!=-1){
				
				bos.wait(temp);
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally{
			try {
				bis.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			try {
				fis.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}finally{
				try {
					bis.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				try {
					fis.close();
				} catch (IOException e1) {
					// TODO Auto-generated catch block
					e1.printStackTrace();
				}
				try {
					bos.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				try {
					fos.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}
	}
