Can you give me some choices to make aix extension

Niotron IDE. No installation, but I don’t really recommend it because a lot of features, such as helper blocks and assets, are not supported, but good for a beginner. It’s here: https://ide.niotron.com/. Extensions template. Requires the installation of both Java and Apache Ant. Supports helper blocks, multiple Java files, and all essential features. Rush. Supports the Kotlin language, less annotations, and Java 8 features in libraries.
