The following java program displays the drawing of a scalable tower whose size is determined by user input. 

import java.util.Scanner;

public class Tower { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int size = scnr.nextInt();

drawTower(size); }

public static void drawLine(int size) { for (int i = 1; i <= size * 10 - 1; i++) { System.out.print("X"); } System.out.println(); }

public static void drawPillars(int size) { for (int i = 1; i <= size; i++) { System.out.print(" XXX"); for (int j = 1; j <= (size * 10 - 1) / 3 - 4; j++) { System.out.print(" \\"); } System.out.print(" XXX"); System.out.println(); } }

public static void drawLevel(int size) { for (int i = 1; i <= size; i++) {

System.out.print(" XXX"); for (int j = 1; j < size; j++) { System.out.print(" \\ \\ XXX"); } System.out.println(); } }

public static void drawBase(int size) { for (int i = 1; i <= size + 1; i++) { for (int j = 1; j <= size * 10 - 1; j++) { System.out.print("X"); } System.out.println(); } }

public static void drawTower(int size) { drawLine(size); drawPillars(size); for (int i = 1; i <= size; i++) { drawLine(size); drawLevel(size); } drawBase(size); } }

Question: Add a method called "int doTheLean (int space)" to make the tower leaning. Every row leans one space more than the row above it. This method prints a bunch of blank spaces in a for loop, and anyone who needs to have spaces printed simply calls the method and it does the job. Initialize the variable space to 0 in the main, and before the doTheLean() method ends, increment space by 1 and return the updated value to its calling method. In this way the calling method knows the updated value of spaces for the next time it calls doTheLean.
