In Java, inserting a word into the middle of another string involves several steps. Below is a simple Java program that demonstrates how to accomplish this task:

[[See Video to Reveal this Text or Code Snippet]]

This program defines a class named InsertWordInMiddle with a main method and a helper method named insertWord. In the main method, we have an original string (originalString) and a word to insert (wordToInsert). We calculate the middle index of the original string to determine where the word should be inserted.

The insertWord method takes the original string, the index where the word should be inserted, and the word to insert as parameters. Inside this method, a StringBuilder object is used to efficiently manipulate strings. We insert the word into the StringBuilder at the specified index using the insert method. Finally, we return the modified string by converting the StringBuilder back to a string using the toString method.

When you run this program, it will output the modified string with the word inserted into the middle of the original string.

This Java program provides a straightforward way to insert a word into the middle of another string, which can be useful in various text processing applications.
