Introduction

Strings are an important part of Java programming. They help developers store and process text, such as names, messages, and user inputs.

In Generative AI (GenAI) applications, strings are used to manage prompts, process AI-generated responses, and prepare text before sending it to an AI model.

What Is It?

A String in Java is an object used to represent a sequence of characters. String methods help developers perform operations such as trimming spaces, changing case, and checking whether text contains specific words.

Syntax / Example

public class GenAIStringExample { public static void main ( String [] args ) { String prompt = " Explain Generative AI " ;

String cleanedPrompt = prompt . trim (); String upperPrompt = cleanedPrompt . toUpperCase ();

System . out . println ( cleanedPrompt ); System . out . println ( upperPrompt ); System . out . println ( cleanedPrompt .…
