Java初学小程序(键盘录入4个数,求最小值)

import java.util.Scanner;
class Demo12 {

public static void main(String[] args) {
	Scanner sc = new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int c = sc.nextInt();
	int d = sc.nextInt();
	int abMin = a < b ? a : b;
	int cdMin = c < d ? c : d;
	int abcdMin = abMin < cdMin ? abMin : cdMin;
	System.out.println("最小值为:" + abcdMin);
}
