請寫出一個程式讀入三個整數，找出最大和最小的數 。

import java.util.Scanner;

public class ThreeIntCompare {

	public static void main(String[] args) {
		// 輸入並讀取三個整數
		Scanner scn = new Scanner(System.in);
		
		System.out.println("Enter the first integer:");
		int num1 = scn.nextInt();
		
		System.out.println("Enter the second integer:");
		int num2 = scn.nextInt();
		
		System.out.println("Enter the third integer:");
		int num3 = scn.nextInt();
		
		// 找max
		int max = num1;
		
		if(num2>max) {
			max = num2;
		}if(num3>max) {
			max = num3;
		}
		
		// 找 min
		int min = num1;
		
		if(num2<min) {
			min = num2;
		}if(num3<min) {
			min = num3;
		}
		
		// 輸出結果
		System.out.println("Maximum: "+max);
		System.out.println("Minimum: "+min);
		
		scn.close();
	}
