java 获取键盘输入

java 中，如何获取键盘输入呢？

看下面代码：

/**
	 * 
	 * @return
	 * @throws IOException
	 */
	public static String getStringKeyboard() throws IOException {
		InputStreamReader isr = new InputStreamReader(System.in);
		BufferedReader br = new BufferedReader(isr);
		String s = br.readLine();
		return s;
	}

	public static int getIntKeyboard() {
		Scanner sca = new Scanner(System.in);
		return sca.nextInt();
	}
