java - 是否可以创建一个 int 名称变量数组

Question

我想知道是否可以构建一个 int 名称变量数组。下面的示例，我希望它们初始化为 0；

int[] h1i1ctrlk, h1i2ctrlk, h1i3ctrlk, h1i4ctrlk, h1i5ctrlk;

Answer 1

I'm not sure if it is correct way to create the array and I can't initialise it.

尝试

int[] h1i1ctrlk, h1i2ctrlk, h1i3ctrlk, h1i4ctrlk, h1i5ctrlk;
h1i1ctrlk = new int[length]; // an array of length full of 0s.
....
h1i5ctrlk = new int[length]; // an array of length full of 0s.

将数组的所有元素设置为值 1.0

Arrays.fill(hii1ctrlk, 1.0);

如果您有特定的值，您可以使用

int[] h1i1ctrlk = { 0, 1, 2, 10 };

或

int[] h1i1ctrlk;
hii1ctrlk = new int[] { 0, 1, 2, 10 };

或者使用循环

int[] h1i1ctrlk = new int[length];
for(int i = 0; i < length; i++)
    h1i1ctrlk[i] = i * i;

您还可以使用Map<String, int[]>像这样

Map<String, int[]> ctrlk = new LinkedHashMap<>();
for(int h = 1; h <= 9; h++) {
   for(int i = 1; i <= 5; i++) {
       String key = "h"+h+"i"+i;
       ctrlk.put(key, new int[length]);
   }
}
