Question

There is an array lut_addresses[] of type int. There are some calculations for a variable table_ptr which is also an int and represents the new base of the array. Now i want to assign lut_addresses[] values beginning from the index table_ptr till the last index to the array lut_addresses[] so that initial values till table_ptr are deleted and value at table_ptr is present at 0th index of lut_addresses[]. How can i do it without changing lut_addresses to an arraylist?

Pseudo code:

A()
{
   int lut_addresses[] = new int[2048];
   // assign values upto a cetain index
   B(lut_addresses);
};
B()
{
   int table_ptr=0;
   //calculate table_ptr;
   // assign lut_addresses[] values from index table_ptr till (lut_addresses.length-1)  
}

First thing that comes to mind would be to use System.arraycopy.

Copies an array from the specified source array, beginning at the
specified position, to the specified position of the destination
array.
