Creating variable in BPMN file and accessing them into Java Delegate

For ex in bpmn file, 

execution.setVariable('trainername','SOME_TRAINER');

Now you can access the trainername in the java delegate otherwise, you may get NPE.

In Java code

var procInstVariable = execution.getVariable('trainername')

or 

String procInstVariable =(String) execution.getVariable('trainername')

Creating workflow variable in Java delegate and accessing them into workflow

In your java delegate code, 

execution.setVariable('trainername','SOME_TRAINER');

You can access in BPMN file like, 

var procInstVariable = execution.getVariable('trainername')

Please let me know, if I understood wrongly or any help on this.
