In this article, we will learn how to print a diamond shape pattern using nested loops in Java. This helps in understanding loops and conditional structures in Java programming.A nested loop refers to a loop placed within another loop. This structure is often called "loops within loops" because the inner loop runs completely each time the outer loop iterates.Diamond Shape A diamond shape is a symmetrical pattern that consists of two parts: an upper triangle and a mirrored inverted triangle below it. In programming, such patterns are typically printed using nested loops to control spaces and symbols. A diamond ... Read More
