print?import java.io.*;
import java.util.*;
class Copy
{
static void copy(String from,String to) throws IOException
{
BufferedReader in=new BufferedReader(new FileReader(from));
BufferedWriter out=new BufferedWriter(new FileWriter(new File(to)));
String line=null;
while((line=in.readLine())!=null)
{
out.write(line+"\n");
}
in.close();
out.close();
}
public static void main(String[] args) throws IOException
{
Scanner sc=new Scanner(System.in);
System.out.print("请输入文件路径：");
String from=sc.next();
System.out.print("请输入拷贝路径：");
String to=sc.next();
copy(from,to);
}
}
import java.io.*;
