我也有一个：
package file;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
public class CopyFile {
/**
* @param args
*/
public void copyFile(String src,String des){
FileInputStream fis=null;
FileOutputStream fos=null;
try {
fis = new FileInputStream(src);
fos = new FileOutputStream(des);
byte[ ]buffer = new byte[512];
int n=0;
while((n=fis.read(buffer))!=-1){
fos.write(buffer, 0, n);
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
try {
fis.close();
fos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
CopyFile cf = new CopyFile();
cf.copyFile("F:/date.java", "d:/com/date.java");
}
}
