Java coding to calculate value of field

I want to create a calculated field which need both conditional expressions(if-else, while loop etc) and arithmetic equations.

It is possible only through java coding. How can I create such calculated field using java code.

Please explain step by step to create field and path to reach java platform as I am a beginner.

I am not sure on “Creating a calculated field on Java code” but you can create a field, add an edit input on that which can run java code. In the java code, you need define the logic that you want to have in the field. It can run if else expression as well as airthmetic expression.

There any many OOTB edit input or edit validation rule which you can refer to look at our the logic is created based on requirement if there is something to reuse, you can use that code
