When working with text in Java, especially in internationalized applications, it's essential to consider bidirectional (BiDi) text, which includes languages that are read from right to left (RTL) such as Arabic, Hebrew, and Persian. Handling the alignment and justification of BiDi text correctly can be challenging due to the bidirectional nature of the script.
Fortunately, Java provides the Bidi class in the java.text package, which allows developers to handle bidirectional text and perform text alignment and justification according to the text direction.
Below is a basic example demonstrating how to align and justify BiDi text in Java:

In this example, we first create a Bidi object to analyze the text and determine its base direction. Then, we use a helper method alignText to align the text properly within a specified width, taking into account its base direction. Finally, we display the aligned text.
By using the Bidi class in Java, developers can ensure that text alignment and justification work correctly for bidirectional text, providing a seamless experience for users in various languages.
