JavaPoet

Uses method chaining and immutable objects like MethodSpec and TypeSpec builders, making code generation intuitive and less error-prone than string concatenation, as demonstrated in the HelloWorld example.

Supports $T placeholders for types with automatic import handling, simplifying the generation of correct Java files and reducing manual import errors.

Provides beginControlFlow() and endControlFlow() methods to easily generate loops, conditionals, and try-catch blocks, as shown in examples for if/else and for loops.

Covers a wide range of Java constructs including classes, interfaces, enums, annotations, and Javadoc, allowing for diverse code generation needs.
