Summary: Learn how to implement bidirectional text conversion and transliteration using the Bidi class in Java. Bidirectional text handling is essential for supporting languages that are written from right to left, such as Arabic and Hebrew, alongside languages written from left to right. This guide explores the Bidi class in Java and demonstrates its usage in bidirectional text processing and transliteration.

Bidirectional text handling is a crucial aspect of software development, especially when dealing with languages that are written from right to left (RTL), such as Arabic, Hebrew, and Urdu, alongside languages written from left to right (LTR), such as English, Spanish, and French. Java provides support for bidirectional text processing through the Bidi class in the java.text package. This class allows developers to handle bidirectional text conversion and transliteration seamlessly.
Understanding Bidirectional Text
Bidirectional text refers to text containing characters that are written from both left to right and right to left orientations. When working with bidirectional text, it's essential to maintain proper display order and readability, especially when combining RTL and LTR scripts within the same document or application.
The Bidi Class in Java
The Bidi class in Java provides methods for handling bidirectional text. It allows developers to analyze, convert, and display bidirectional text correctly. Here's an overview of some key methods provided by the Bidi class:
Bidi(String text, int flags): This constructor creates a Bidi object from the specified text and flags. The flags parameter determines the text directionality options.
getDirection(): Returns the overall directionality of the text.
isLeftToRight(): Indicates whether the text is predominantly left-to-right.
isRightToLeft(): Indicates whether the text is predominantly right-to-left.
writeReordered(char[] src, int start, char[] dest, int destStart, int len): Writes the reordered text into the destination array based on the source text.
Implementing Bidirectional Text Conversion
Here's a simple example demonstrating how to use the Bidi class to convert bidirectional text:

Implementing Transliteration with Bidi
Transliteration involves converting text from one script to another while maintaining the phonetic or visual similarity between the original and transliterated text. The Bidi class can be used in conjunction with transliteration libraries or algorithms to achieve this. Here's a conceptual example:

In this example, the Normalizer class is used to normalize the text before performing bidi analysis and transliteration.
Conclusion
In this guide, we've explored how to implement bidirectional text conversion and transliteration using the Bidi class in Java. Proper handling of bidirectional text is essential for developing applications that support diverse languages and scripts. By leveraging the capabilities of the Bidi class, developers can ensure correct rendering and readability of bidirectional text in their Java applications.
