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
" + 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
" + number1 + " - " + number2 + " = ?
");
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");
}
}
