java 求两个数较小值

 

//find smallest among two numbers

import java.util.Scanner;

public class Numbers {

    public static void main(String[] args) {
        int num1, num2;
        Scanner ip = new Scanner(System.in);
        System.out.print("Enter num1: ");
        num1 = ip.nextInt();
        System.out.print("Enter num2: ");
        num2 = ip.nextInt();
        if (num1 < num2)
            System.out.println(num1 + " is smaller that " + num2);
        else if (num2 < num1)
            System.out.println(num2 + " is smaller that " + num1);
        else
            System.out.println("Both are same");

        ip.close();
    }

}



OUTPUT:
Enter num1: 35
Enter num2: 45
35 is smaller that 45

求三个数中最小值

//find smallest among three numbers

import java.util.Scanner;

public class Numbers {

    public static void main(String[] args) {
        int num1, num2, num3;
        Scanner ip = new Scanner(System.in);
        System.out.print("Enter num1: ");
        num1 = ip.nextInt();
        System.out.print("Enter num2: ");
        num2 = ip.nextInt();
        System.out.print("Enter num3: ");
        num3 = ip.nextInt();
        if (num1 >= num2 && num1 >= num3)
            System.out.println(num1 + " is greater");
        else if (num2 >= num1 && num2 >= num3)
            System.out.println(num2 + " is greater");
        else
            System.out.println(num3 + " is greater");
        ip.close();
    }

}



OUTPUT:
Enter num1: 5
Enter num2: 6
Enter num3: 6
6 is greater

//find smallest among three numbers using ternary operator

import java.util.Scanner;

public class Numbers {

    public static void main(String[] args) {
        int num1, num2, num3, greater;
        Scanner ip = new Scanner(System.in);
        System.out.print("Enter num1: ");
        num1 = ip.nextInt();
        System.out.print("Enter num2: ");
        num2 = ip.nextInt();
        System.out.print("Enter num3: ");
        num3 = ip.nextInt();

        // code to find greatest
        greater = (num1 >= num2 ? (num1 >= num3 ? num1 : num3) : (num2 > num3 ? num2 : num3));
        System.out.println("The greatest number is " + greater);
        ip.close();
    }

}



OUTPUT:
Enter num1: 1
Enter num2: 3
Enter num3: 2
The greatest number is 3
