按注释提示完成文件复制的程序
//FileStream源代码如下：
import java.io.*;
class FileStream
public static void main(String args [])
try
File inFile = new File("file1.txt"); //指定源文件
File outFile = new File("file2.txt"); //指定目标文件
FileInputStream fis =(1);
FileOutputStream fos = new FileOutputStream(outFile);
int c;
//逐字节从源文件中输入，再输出到fos流
while ((c = fis.read ())!=-1)
(2);
fis.close();
fos.close();

catch (Exception e)
System.out.println("FileStreamsTest: "+e);
