Possible Lossy conversion from long to int

Question

I wish to enter one int and another long ex: 1 and 1000000000, and now I wish to create an array of size 1000000000. And then at each index of arra

Answer 1

The size of an array can only be an int. That is you, can not create arrays that are larger than Integer.MAX_VALUE (2147483647), probably a few elements less (depending on the VM). You can cast your value to int

arr = new long[(int)(y+1)];

but this will produce invalid results when the value of y is actually larger than the maximum allowed size.
