possibly lossy conversion strange error java

 

This question already has an answer here:

  • Possibly lossy conversion from long to int 2 answers

    • "Arrays must be indexed by int values... An attempt to access an array component with a long index value results in a compile-time error." --- Wikipedia https://en.wikipedia.org/wiki/Criticism_of_Java#Large_arrays

    You cannot initialize an array with a long size. You can only implement an array using an integer size n that satisfies: 

    0 <= n <= Integer.MAX_VALUE

    See Java SE specification > Array Access.

    All arrays are 0-origin. An array with length n can be indexed by the integers 0 to n-1.

    Arrays must be indexed by int values; short, byte, or char values may also be used as index values because they are subjected to unary numeric promotion (§5.6.1) and become int values.

    An attempt to access an array component with a long index value results in a compile-time error .
