You can implement a condition by using either of the following ways:

     =>   By creating a rule condition - Specifies that you can implement conditions either directly in code or by using a tool, called the Rule Condition Editor. Rule conditions are stored in a separate Extensible Markup Language (XML) file. When a rule condition occurs in a workflow, the expression in a condition is evaluated and a Boolean value is returned.

     =>   By creating a code condition - Refers to defining a condition directly in code. A code condition can be created by writing a method in the code. The method contains code for the condition and returns a Boolean value.

Inside an interface every method will be by default abstract and public
