简单Java应用程序不工作

简单Java应用程序不工作,java,Java,这与我用更优雅的代码解决的问题有关。我在胡闹，试图用非常基本的代码以不同的方式解决问题。问题是我得到的号码（2091059712）不正确。正确答案是235146240000。这快把我逼疯了。这是坏代码。我试图找到1000位数字中具有最大乘积的13个相邻数字 public class AdjacentProducts { public static void main(String[] args) { int[] x = new int[] { 7, 3, 1, 6, 7,

每一次乘法都是另一次溢出的机会。您的答案在输入

结果之前就溢出了。一种解决方案是将数组的定义更改为
long[] x = new long[]

同样的问题也出现在Java拼图游戏书中的拼图游戏3中：
以下是Bloch和Gafter给出的解释：
问题是，每天常量MICROS_的计算不会溢出。虽然计算结果适合于有剩余空间的长，
public class LongDivision {
   public static void main(String[] args) {
       final long MICROS_PER_DAY = 24 * 60 * 60 * 1000 * 1000;
       final long MILLIS_PER_DAY = 24 * 60 * 60 * 1000;
        System.out.println(MICROS_PER_DAY / MILLIS_PER_DAY;
    } 
}

       result = 1L * x[a] * x[b] * x[c] * x[d] * x[e] * x[f] * x[g] * x[h]
                * x[i] * x[j] * x[k] * x[l] * x[m];
