	 */
	public static void main(String[] args) throws Exception{
		System.out.println("请输入第一个值:");
		InputStreamReader isr=new InputStreamReader(System.in);
		BufferedReader br=new BufferedReader(isr);
		String str1=br.readLine();
		double num1=Double.parseDouble(str1);
		System.out.println("请输入第二个值:");
		String str2=br.readLine();
		double num2=Double.parseDouble(str2);
		System.out.println("两个数相加的结果是:"+(num1+num2));
