Hello, Adventurer! Today, we will learn about splitting and joining strings — two vital operations for processing textual data in Java. Are you ready? Let's start this journey!

In Java, the split() method divides a string into several substrings based on a delimiter — a character that separates words. It stores these substrings into an array. Here's an example to clarify:

In this snippet, we have a sentence that we divide into separate words using the split() method with a space as the delimiter. The results are stored in the array words.

The join() method merges an array of strings back into a single string using a specified delimiter. It is the reverse of the split() method. Here's how it works:

In the example above, we took an array of words and combined them into a single string, using a space as the delimiter.
