Flag Pattern in Java

In this section, we will discuss how we can print the flag pattern in Java. Flag patterns are rarely asked by the interviewers because they are complex to code.

Here, we understand the code for the flags of two different countries, i.e., India and America. First, we will implement the logic for the Indian flag and then the American flag.

Indian Flag

In order to print the Indian flag, we break the complete process into the following parts:

  1. The first layer of the flag.
  2. The second layer of the flag.
  3. The third layer of the flag.
  4. The flagstick.
  5. Stairs part.

We print all the parts of the Indian flag by using only one nested for loop.

American Flag

In order to print the American flag, we break its code into three parts which are as follows:

  1. Flag part.
  2. Stick part.
  3. Stairs part.

The code of the Stick and the Stairs parts of the American flag is similar to the Indian flag. The logic of the Flag part is completely different from the Indian flag.

Let's implement the code of the American flag by using only one nested loop and understand the difference between the code of the Indian flag and the American flag.
