用Scanner键盘输入两个数然后再输出

import java.util.*;

public class Number{
public static void main(String[] args){

Scanner M = new Scanner(System.in);
System.out.print("请输入第一个数：");
float number1 = M.nextFloat();
System.out.print("请输入第二个数：");
float number2 = M.nextFloat();
System.out.println("这两个数是：" + number1 + " " + number2);
//System.out.println("两个数的和是："+ (number1+number2));
//System.out.println("两个数的差是："+(number1-number2));
//System.out.println("两个数的积是："+(number1*number2));
//System.out.println("两个数的商是："+(number1/number2));
     }
