201712-1最小差值

题目：

代码：

import java.util.Scanner;

public class MiniDif {
    
    public static void main(String[] args) {
        int n;
        int[] values;
        Scanner scan = new Scanner(System.in);
        
        n = scan.nextInt();
        values = new int[n+1];
        
        for(int i=1;i<=n;i++) {
            values[i] = scan.nextInt();
        }
        
        md(values);
    }

    public static void md(int[] values) {
        Integer minimum = Integer.MAX_VALUE;
        int difference;
        
        for(int i=1;i<=values.length-2;i++)
            for(int j=i+1;j<=values.length-1;j++) {
                difference = Math.abs(values[i]-values[j]);
                if(difference < minimum)
                    minimum  = difference;
            }
        
        System.out.println(minimum);
    }
}

主类名称改为Main
