In the Jack language, arrays are instances of the Array class. Once declared, the array entries can be accessed using the usual syntax arr[i]. Each array entry can hold a primitive data type as well as any object type. Different array entries can have different data types.
### function Array new(int size)
Constructs a new Array of the given size.
if (~(size>0)){
do Sys.error(3);
}
return Memory.alloc(size);
}
/** Disposes this array. */
method void dispose() {
do Memory.deAlloc(this);
