Shifting in arrayList

If you can use built-in solution then your code can be as simple as

public static <T> List<T> rotate(List<T> aL, int shift) {
    List<T> newValues = new ArrayList<>(aL);
    Collections.rotate(newValues, shift);
    return newValues;
}

Try this:

public static <T> ArrayList<T> rotate(ArrayList<T> aL, int shift)
{
    if (aL.size() == 0)
        return aL;

    T element = null;
    for(int i = 0; i < shift; i++)
    {
        // remove last element, add it to front of the ArrayList
        element = aL.remove( aL.size() - 1 );
        aL.add(0, element);
    }

    return aL;
}

Try this:

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class ALUtils {

public static <T> ArrayList<T> rotate(List<T> aL, int shift) {
    ArrayList<T> newValues = new ArrayList<>(aL);
    Collections.rotate(newValues, shift);
    return newValues;
}
}
