Program to Extract a Specific Line from a Multi-Line String in Java

Below is the implementation of extracting a specific line from a multiline string by using extractLine() and split() methods.

Original String is :

• Then it retrieves the line at the specified index.
• It uses the split() method to separate the multi-line string into individual lines based on the newline character (\n).
• Then, it checks if the array length is sufficient to access the specified line.
• Then it returns the line, otherwise, it returns an empty string.
• This approach efficiently handles the task of extracting a particular line from a multi-line string in Java.
