java实现图片等文件类型的本地复制详解编程语言

java实现图片等文件类型的本地复制

由于很简单直接上代码

package demo; 
 
import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.InputStream; 
import java.io.OutputStream; 
 
public class PicIo { 
	 
	 public static void main(String[] args)   
	    {   
	        String src="D://FILESERVER//IMGNFS//estun_cs//staff_family_file//1508985399735.jpg";   
	        String target="D://FILESERVER//IMGNFS//estun_cs//banner_img//1508985399735.jpg";   
	        try { 
				copyFile(src,target); 
			} catch (Exception e) { 
				e.printStackTrace(); 
			}   
	    }   
	 public static void copyFile(String src,String target) throws Exception {      
	        File srcFile = new File(src);     
	        File targetFile = new File(target);     
	        InputStream in = new FileInputStream(srcFile);      
	        OutputStream out = new FileOutputStream(targetFile);     
	        byte[] bytes = new byte[1024];     
	        int len = -1;     
	        while((len=in.read(bytes))!=-1){     
	            out.write(bytes, 0, len);     
	        }     
	        in.close();     
	        out.close();     
	   }   
 
}
