错误当打印大量，Min和二段成为负

Question

I am getting an error when printing a large number, minutes and seconds become negative. I think it is due to the size of the number that is printing.

import java.util.Scanner;

public class Minutes
{
    public static void main(String[] args)
    {

        //User information
        Scanner in = new Scanner(System.in);
        System.out.println("Please enter a number of hours, days, weeks or years: ");
        int s = in.nextInt();

        //Compute input
        int hours = s * 60;
        int days = s * 1440;
        int weeks = s * 10080;
        int years = s * 525600;

        //Print results
        System.out.println("------------------------------------------------");
        System.out.println("Here are your results!");
        System.out.println("If you entered hours, this is the number of minutes" + ": " + hours);
        System.out.println("If you entered days, this is the number of minutes" + ": " + days);
        System.out.println("If you entered weeks, this is the number of minutes" + ": " + weeks);
        System.out.println("If you entered years, this is the number of minutes" + ": " + years);
    }
}

Answer 1

就是这样，您遇到了integer overflow ，当这种情况发生时，java从Integer.MIN_VALUE开始计数，为什么我显示负数，将其转换为long ant应该没问题。
