Number Pattern Programs In Java :
Java programs to print the numbers or any other symbols in different patterns are one of the frequently asked interview programs mostly for freshers. 



Because, they test the candidate’s logical ability as well as coding skills which are ‘must have 

skills’ for any software engineer. In this post, I have collected some of the different number pattern programs in java and have tried to solve them. I hope they will be helpful for you guys.

System.out.println("How many rows you want in this pattern?");
