How to Split a String by Spaces, Ignoring Spaces Within Quotes?

Splitting Strings with Spaces Not Enclosed by Quotes

In this context, we seek a solution to divide a string into components using spaces that are not encompassed by single or double quotes. This is a nuanced task that requires careful regex crafting.

One effective solution involves constructing a regex that captures two types of elements:

1. Quoted Strings: Sequences of characters enclosed in either single or double quotes, with no internal quotes.
2. Unquoted Words: Sequences of characters not containing spaces or quotes.

To match these elements, we can utilize the following regex:

In this regex:

• [^\s"'] : Matches unquoted words.
• |"([^"]*)"|: Matches double-quoted strings, excluding the quotes.
• |'([^']*)'|: Matches single-quoted strings, excluding the quotes.

Implementing this solution in Java, we can employ the following code:

This approach adeptly captures both types of elements, providing a robust solution to the given problem.
