以下Java程序将文件复制到另一个文件。
import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; 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
