用Java复制文件
以下Java程序将文件复制到另一个文件。
程序

import java.io.IOException;
public class CopyExample {
public static void main(String[] args) {
FileInputStream ins = null;
FileOutputStream outs = null;
try {
File infile = new File("C:\\Users\\nhooo7\\Desktop\\abc.txt");
File outfile = new File("C:\\Users\\nhooo7\\Desktop\\bbc.txt");
ins = new FileInputStream(infile);
outs = new FileOutputStream(outfile);
byte[] buffer = new byte[1024];
int length;
while ((length = ins.read(buffer)) > 0) {
outs.write(buffer, 0, length);
}
ins.close();
outs.close();
System.out.println("File copied successfully!!");
} catch(IOException ioe) {
ioe.printStackTrace();
}
}
}
}输出结果
File copied successfully!!
