In this video, we will see a JAVA program to Print Hollow & Diamond Star Pattern. When it comes to pattern printing we do opt for standard ways of printing them via loops only.

Here we print a hollow diamond star pattern using “for loop”.

Basic method to print Hollow Diamond Star Pattern: To print the box shape we need to print ‘-‘ for i==1 (first row) & i==n (last row) and ‘|’ for j==1 (first column) and j==n (last column).

Here time and space complexity are as follows: 1) Time Complexity: O(n*n) since we are traversing rows and columns of a grid for printing spaces ‘ ‘ and star ‘*’. 2) Auxiliary Space: O(1), No extra Space used.
