java insert array

// ! IMPORTANTE !
// in JAVA an array is not the same as an ArrayList object!!
// 1 - declare, instanciate and populate
int arr[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; 
// 2 - declare and instanciate an int array with maxSize
// note: the index goes between 0 and maxSize-1
int newarr[] = new int[maxSize];
// 2.1 - insert the value n on the position pos
newarr[pos] = n; 
// 2.2 - insert values recursively
for (i = 0; i < maxSize; i++) { newarr[i] = arr[i]; }
