输入一堆数值，求平均值，最大值，最小值，和

Scanner input = new Scanner(System.in);
		String [] str = input.nextLine().split(" ");
		int [] count = new int[str.length];
		for (int i = 0; i < str.length; i++) {
			count[i] = Integer.parseInt(str[i]);
		}
		
		//求最小值
		int min = 0,max = 0,sum = count[0];
		if(count[0] > count[1]){
			max = count[0];
			min = count[1];
		}else{
			max = count[1];
			min = count[0];
		}
		
		for (int i = 1; i < count.length; i++) {
			if(min > count[i]){
				min = count[i];
			}
			if(max < count[i]){
				max = count[i];
			}
			sum += count[i];
		}
		System.out.println("最小值是：" + min);
		System.out.println("最大值是：" + max);
		System.out.println("和是：" + sum);
		System.out.println("平均值是：" + sum * 1.0 / count.length );
