Eclipse's auto-code suggestion feature makes programming very easy and fast. Thanks to Eclipse, we can deliver fast and well-compiled code as it compiles the code on every hit which stops developers from writing bad code instantly. On top of this, we can integrate other software like Tomcat, and MySQL in Eclipse very easily which makes development even faster. Now, we can deploy our Java app directly into Tomcat from Eclipse itself which saves a lot of time in development. The same thing is true in MySQL. we can see data in Eclipse itself using SQL queries. There's no need to install a query browser application.
