fileoutputdemo.java

nanjing university cs 的java课件。 对新手很有用。付课件中源码。

import java.io.*;
public class FileOutputDemo {
	public static byte[] getInput() throws Exception {
		byte buffer[] = new byte[12];
		for (int i = 0; i < 12; i++) {
			buffer[i] = (byte) System.in.read();
		}
		return buffer;
	}

	public static void main(String args[]) throws Exception {
		byte buf[] = getInput();
		OutputStream f0 = new FileOutputStream("file1.txt");
		OutputStream f1 = new FileOutputStream("file2.txt");
		OutputStream f2 = new FileOutputStream("file3.txt");
		for (int i = 0; i < 12; i += 2) {
			f0.write(buf[i]);
		}
		f0.close();
		f1.write(buf);
		f1.close();
		f2.write(buf, 12 / 4, 12 / 2);
		f2.close();
	}
