 1.判断计算是否正确

import java.util.Scanner;

  public class FM
    {
      public static void main(String[] args)
        {
          int number1=(int)(System.currentTimeMillis()%10);
          int number2=(int)(System.currentTimeMillis()/7%10);

          Scanner input =new Scanner(System.in);

          System.out.print("what is \n" + number1 + "+" + number2 +" = ? ");
          int answer=input.nextInt();

          System.out.println(number1 + "+" + number2 + "=" + answer + " is " + (number1 + number2 == answer));

        }
    }

 

 

 

 

2.随便写一个数字 然后判断

import java.util.Scanner;
  public class HE
    {
      public static void main(String[] args)
        {
          Scanner input = new Scanner(System.in);
          System.out.println("Enter an integer: ");
          int number = input.nextInt();

          if (number % 5 == 0)
          System.out.println("Hifive");
          if (number % 2 == 0)
          System.out.println("Hieven");
        }
    }

 

 

 

 

 

 

3随便生成一个计算题 然后判断错对

import java.util.Scanner;

  public class MF 
  {
    public static void main(String[] args)
    {
      int number1 = (int)(Math.random()*10);
      int number2 = (int)(Math.random()*10);

      if(number1 < number2)
      {
        int temp=number1;
        number1=number2;
        number2=temp;
      }

        System.out.print("What is \n" + number1 + " - " + number2 + " = ?\n");
        Scanner input = new Scanner(System.in);
        int answer = input.nextInt();

        if(number1 - number2 ==answer)
        System.out.println("你对了");
        else
        {
        System.out.println("你错了");

        System.out.println(number1 + "-" + number2 +" should be " + (number1 -number2));
        }
    }
  }

 

 

 

 

 

 

 

 

 

 

 

 

 

4.计算身体平衡值 看BMI值是否正常

import java.util.Scanner;
  public class BMI 
  {
    public static void main(String[] args)
    {
      Scanner input =new Scanner(System.in);

      System.out.print("输入体重");
      double weight=input.nextDouble();

      System.out.print("输入身高");
      double height=input.nextDouble();

      double bmi=weight/(height*height);

      System.out.println("BMI is" + bmi);
      if (bmi<18.5)
      System.out.println("太瘦");
      else if (bmi<25)
      System.out.println("刚好");
      else if (bmi<30)
      System.out.println("超重");
      else 
      System.out.println("太胖");
    }
  }
