20170731 JAVA利用数组和循环比较数组元素的大小

package com.chy.array;

import java.util.Scanner;

public class Array6 {

public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
int a[];
a = new int[4];
System.out.println("请输入4家店的价格");
for (int i = 0; i < 4; i++) {
System.out.print("第" + (i + 1) + "家店的价格:");
a[i] = sc.nextInt();
}
int min = a[0];
for (int i = 1; i < 4; i++) {
if (a[i] < a[i - 1]) {
min = a[i];
}
}
System.out.println("最低价格是：" + min);
}
