Java 实例 使用三元运算符查找三个数字中的最大数字

variable num = (expression) ? value if true : value if false

result = num3 > (num1>num2 ? num1:num2) ? num3:((num1>num2) ? num1:num2);

import java.util.Scanner;
public class JavaExample 
{
    public static void main(String[] args) 
    {
        int num1, num2, num3, result, temp;
        /* Scanner is used for getting user input. 
         * The nextInt() method of scanner reads the
         * integer entered by user.
         */
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter First Number:");
        num1 = scanner.nextInt();
        System.out.println("Enter Second Number:");
        num2 = scanner.nextInt();
        System.out.println("Enter Third Number:");
        num3 = scanner.nextInt();
        scanner.close();

        /* In first step we are comparing only num1 and
         * num2 and storing the largest number into the
         * temp variable and then comparing the temp and
         * num3 to get final result.
         */
        temp = num1>num2 ? num1:num2;
        result = num3>temp ? num3:temp;
        System.out.println("Largest Number is:"+result);
    }
}

Enter First Number:
89
Enter Second Number:
109
Enter Third Number:
8
Largest Number is:109
