编写一个Java程序将当100,101,102,103,104,105个数以数组的形式写入到Dest.txt文件中，并以相反的顺序读出显示在屏幕上

public class IODemo {
	public static void main(String[] args) {
		int data[] = { 100, 101, 102, 103, 104, 105 };
		try {
			DataOutputStream out = new DataOutputStream(new FileOutputStream("dest.text"));
			for (int i = 0; i < data.length; i++)
				out.writeInt(data[i]);
			out.close();
			DataInputStream in = new DataInputStream(new FileInputStream("dest.text"));
			for (int i = data.length - 1; i >= 0; i--) {
				data[i] = in.readInt();

			}
			for (int i = 0; i < data.length; i++) {
				System.out.print(" " + data[i]);
			}

			System.out.println();
			in.close();

		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			System.out.println(e.getMessage());
		}

	}
}

注：发现DataInputStream里没有readInt（int v）这个方法好奇怪；
