Not all blank lines need to be used. int N-some positive integer (N 2 1) IntList LA new IntList [N] / arraycopy (FROM_ARR, FROM_INDEX, TO_ARR, TO_INDEX, LENGTH) import static java.lang.System.arraycopy: public class IntList First element of list, public int head; Remaining elements of list. / public IntList tail; A List with head HEADO and tail TAILO. public IntList(int heado IntList tai10) head heado; tail tai1o; ) /A List with null tail, and head 0. / public IntList() { this(o, null); } Returns a ne IntList containing the ints in ARGS. / public static IntList list (Integer.. args) / Implenentation not shoun Returns true iff L (together with the itens reachable from it) is an IntList with the same itema as thia list in the same order &Override public boolean equals(Object L) f / Implenentation not shouwn **Return the length of the non-circular list headed by L. 0verride public int aize) ( / Implementation not shown

Explanation / Answer

I am not completely able to understand the question, still on the basis of whatever is possible, I will try to answer. Please repost in case something else is expected with the question.

Problem Statement states about concept of

Let's take these one by one :-

arraycopy() method is present in java.lang.System library of Java. This method copies a source array to destination array as per the positions provided (the elements are over-written in destination array) and the length that how many indexes needs to be copied.

The method definition for arraycopy(Object source_array, int source_position, Object destination_array, int destination_position, int length)

Sample implementation :-

    public static void main(String[] args)
    {
        int source_array[] = { 1, 3, 5, 7, 9, 11 };
        int destination_array[] = { 2 ,4 ,6 ,8 ,10 ,12 };
  
        int source_pos, dest_pos, length;
source_pos = 3; destPos = 4;

        length = 2;
        // Use of arraycopy() method
        System.arraycopy(source_array, source_pos, destination_array,
                                            dest_pos, length);
         
        // Print elements of destination after arraycopy method
        for (int i = 0; i < destination_array.length; i++)

System.out.print(destination_array[i] + " ");

    }

Over-riding the methods equals and size, simply maintain a global int variable and everytime an integer is added, increment by 1, return the global variable from size() methods ,

public class IntList {
int head;
IntList tail;
int actSize = 0;
public IntList(int head0, IntList tail0) {
head = head0;
tail = tail0;
}
public IntList() {
this(0,null);
}
public IntList list(Integer ...args){
IntList list = new IntList(args[1], null);
//increase the size based on integers provided to add
actSize++;
return list;
}
@Override
public boolean equals(Object L){
return this == null ? L == null : this.equals(L);
}
public int size(){
return actSize;
}
}
