Creating Multiple Overlapping Squares in Java

When working with Java, one interesting challenge that programmers often encounter is drawing multiple overlapping squares with the same top-left corner. This task becomes more engaging, especially when dealing with squares of varying lengths. In this guide, we’ll break down the problem step by step and provide a simple method to implement this in Java.

Understanding the Problem

Imagine you want to render overlapping squares on a console using Java. For example, given two lengths — 5 and 7 — we want to generate a visual representation where the squares overlap precisely at the corner, like so:

In another scenario, if we have lengths 2, 4, and 6, the output would look like this:

The challenge is to create these shapes using a function that takes square sizes as arguments.

Step-by-Step Solution

Let’s dive into a simple solution to achieve this within Java.

Step 1: Setting Up a 2D Boolean Array

To represent the squares, we’ll utilize a 2D boolean array. This array will help us track which positions should be filled to create our overlapping squares.

Step 2: Marking the Squares

For each square, we will determine which cells in our array should be marked as filled. We'll start with the largest square first and then work our way to the smaller squares, marking the appropriate cells.

Step 3: Printing the Result

Finally, once our 2D array reflects all the squares, we will iterate through it to print the output.

Sample Code Implementation

Here’s a straightforward implementation of the above steps in Java:

Explanation of the Code

2D Array Initialization: We initialize a boolean array with the size of the largest square.

Filling the Array: We loop through the indices of the array to mark the edges of both squares as true if they correspond to a border.

Output: Finally, we print the 2D array, replacing true with # and false with a space.

Conclusion

Drawing multiple overlapping squares in Java is a fun exercise that can improve your programming skills. By following the structured steps laid out above, you can efficiently create a method that can handle varying sizes of squares and generate a beautiful output.

So grab your Java compiler, try out the code, and experiment with different sizes of squares to gain further insights into this intriguing problem!
