Replace constructor with builder
The Replace Constructor with Builder refactoring helps hide a constructor, replacing its usages with the references to a newly generated builder class, or to an existing builder class.
Place the caret at the constructor invocation in the editor and press Alt+Enter.
From the list of available context actions, select Replace constructor with builder.
In the dialog that opens, if you need, change the suggested setter names. Specify whether you want to initialize the generated fields in the builder.
If you specify an initial value that matches the parameter value in the constructor invocation, you can skip setter method for such parameter by selecting the Optional Setter checkbox. You can also specify whether you want to create a new or use the existing builder.
Preview and apply the changes.
