向数组添加无穷大值

Question

I want to add an infinity value to the last index of an array. I tried something like this in my java code. My array is an integer type.

Integer myInf = Integer.MAX_VALUE;
array_name[length_of_array]=myInf;

It is not working. What might be the problem in my code?

Answer 1

Use one less index value in array_name.

Integer myInf = Integer.MAX_VALUE;
array_name[length_of_array - 1]=myInf;

Answer 2

Is length_of_array set to the correct value? Also, arrays are 0-indexed, so the last index is 1 less than the size of the array.

Try this instead:

array_name[array_name.length - 1] = Integer.MAX_VALUE;
