Tools and Web Site helpful for Java folks

Websites

1. json2csharp.com - this website helps to convert JSON string to Java Classes
2. yamllint - now a days Yml/Yaml is used across java projects as config tool, it's really hard to validate yml file structure as a single space can make yml corrupted, yaml lint helps to validate formatting of yml file

InteliJ Idea Plugins

1. GitLink - Gitlink Plugin Integrates most of the popular Git Based platform (GitLab, Bitbucket etc) to InteliJ Idea so Developers can open Web console directly from IDE
2. AWS toolkit - Rather than logging into aws console dev's can Trigger lambda, ecs tasks directly from IDE using this plugin

NotePad++ - NotePad++ Regulars expression Search/Replace functionality and Column Mode (Alt+select) helped me to improve my productivity significantly

Along with these tools using various shortcut's in InteliJ helped me to improve my productivity and speed of the development
