i have created this input output variable like 

<bpmn:extensionElements>
    <camunda:inputOutput>
      <camunda:inputParameter name="c">5</camunda:inputParameter>
      <camunda:inputParameter name="d">10</camunda:inputParameter>
      <camunda:inputParameter name="e">2</camunda:inputParameter>
    </camunda:inputOutput>
  </bpmn:extensionElements>

how can i use these variables in my JavaDelegate class

This input mapping creates String variables with the values "5", "10", "2" respectively. If you want this to become numbers, you can write it as an EL expression like so: <camunda:inputParameter name="c">${5}</camunda:inputParameter>.
