在Java中追加整数数组元素 [英] Appending Integer array elements in Java

问题描述

我有一个数组，说

int a[]={2,0,1,0,1,1,0,2,1,1,1,0,1,0,1};

我要追加每5相邻元素，并将其分配到一个新的数组 B 与长度=（则为a.length / 5） ; ，我想追加5相邻元素，使我有：
INT B〔] = {20101,10211,10101}; 我需要用的长度各种长数组做到这一点，在大多数情况下大于15

I need to append each of the 5 neighboring elements and assign them to a new array b with length=(a.length/5); and i want to append the 5 neighboring elements so that I have: int b[]={20101,10211,10101}; I need to do this for various length arrays, in most cases with length of a being greater than 15.

任何帮助将大大AP preciated，我在Java编程。

Any help would be greatly appreciated, I'm programming in Java.

先谢谢了。

推荐答案

这是pretty简单明了：

It's pretty straighforward:

// Assuming a.length % 5 == 0.
int[] b = new int[a.length / 5];
for (int i = 0; i < a.length; i += 5) {
    b[i/5] = a[i]*10000 + a[i+1]*1000 + a[i+2]*100 + a[i+3]*10 + a[i+4];
}
