19 Different Star Pattern Programs in Java

I have shared number pattern programs in java and alphabet pattern programs in java. In this tutorial I will be sharing 19 star pattern programs in java or different star pattern program in java. This blog post is a good way to kick start your coding skills.
I have taken some star pattern programs in java and tried to solve them. Please add more pattern and code in the comment section.
