The one tool you would want to have is NetBeans IDE.
Get it from the NetBeans or Oracle website. (Do a search for NetBeans IDE.)
Another great IDE for Java coding is the IntelliJ IDEA from JetBrains. IntelliJ has a community version that is free.
To start up Netbeans or IntelliJ, double-click on its desktop icon.
To create a new project: click File, New Project.
Select Java under the Categories header
and Java Application under the Projects header.
Give the project a name.
To create a new class file: click File, New File.
Select Java under the Categories header
and Java Class under the Projects header.
Name the class.
Notice: Our colour coding follows that of Oracle's NetBeans IDE.
