Question

I have this code done in two methods, but it has to be done in one, and I can not figure out how to have it work and run correctly in one method.

Chess Board:

You will also create 5 "lanes" of "pieces" and each lane has that number of pieces on it;
i.e. lane 5 = 5 pieces, lane 4 = 4 pieces, etc.
The user and the computer can take any number of pieces from one lane.
The object is to not take the last piece.

import java.util.Arrays;
import java.util.ArrayList;
import java.util.List;
import java.io.IOException;
import java.util.Scanner;

public class ChessBoardTest{

public static void main(String str[]) throws IOException {
  
Scanner scan = new Scanner (System.in);

int lane5[] = {0,0,0,0,0};
int lane4[] = {0,0,0,0};
int lane3[] = {0,0,0};
int lane2[] = {0,0};
int lane1[] = {0};

int lanenum;
int piecenum;

System.out.println("Please select a lane that you want to take from");
lanenum = scan.nextInt();

System.out.println("How many do you want to take? Selecet a number 1 - 3.");
piecenum=scan.nextInt();

int removeThePieces;

if (lanenum == 5&&piecenum<=5) {
lane5 = removeThePieces(lane5, piecenum);
System.out.println(lane5);
}
else if (lanenum == 4&&piecenum<=4) {
lane4 = removeThePieces(lane4, piecenum);
System.out.println(lane4);
}
else if(lanenum == 3&&piecenum<=3) {
lane3 = removeThePieces(lane3, piecenum);
System.out.println(lane3);
}
else if(lanenum == 2&&piecenum<=2) {
lane2 = removeThePieces(lane2, piecenum);
System.out.println(lane2);
}
else if(lanenum == 1&&piecenum<=1) {
lane1 = removeThePieces(lane1, piecenum);
System.out.println(lane1);
}
}
public int[] removeThePieces(int[] arr, int number) {
int[] anotherArray = new int[arr.length - number];
for (int i = 0, k = 0; i < arr.length-number; i++) {
anotherArray[k++] = arr[i];
}
return anotherArray;
}
}
