转换INT []数组在Java中短期[]数组 [英] Convert int[] array to short[] array in Java

问题描述

我有，我有100个元素分配空间中的 INT 阵列。还有另外一个数组 inShort [] 。我怎么能转换 inInt [] 到 inShort [] ？

是否有必要为分配新的内存inShort [] 或没有通过，我可以转换为 inInt [] ？

  INT inInt [] =新INT [100];
短inShort [];
 




解决方案

 短inShort [] =新的短[100];的for（int i = 0; I＆LT; 100;我++）
{
    inShort [I] =（短）inInt [I]
}
 

但是，你很可能会漫短，如果int是短期的范围之外（即超过32,767小于-32,768或更大）。它实际上很容易溢出短，因为一个int范围从-2,147,483,648到2,147,483,647。

I have an int array for which i have allocated space for 100 elements. There is another array inShort[]. How can I convert inInt[] to inShort[]?

Is it necessary to allocate new memory for inShort[] or there is a way through which I can cast to inInt[]?

int inInt[] = new int[100];
short inShort[];

解决方案

short inShort[] = new short[100];

for(int i = 0; i < 100; i++)
{
    inShort[i] = (short)inInt[i];
}

However, you are very likely to overflow the short if the int is outside the range of the short (i.e. less than -32,768 or greater than 32,767). It's actually really easy to overflow the short, since an int ranges from -2,147,483,648 to 2,147,483,647.
