		Scanner scanner = new Scanner(System.in);
		System.out.println("请问有几个数：");
		int number = scanner.nextInt();
		System.out.println("请输入这"+number+"个数字：");
		int[] arr = new int[number];
		for(int i = 0;i < arr.length;i++) {
			arr[i] = scanner.nextInt();
			if(arr[i]>max) {
				max = arr[i];
			}
		}		
		System.out.println("输入的最大数是："+max);
