This scenario displays the number of occurrences of different ages and the lowest age
within a group of customers. In this scenario, the customer data is entered manually.

You will see two ways to handle this data with the tMemorizeRows:

• Inside the same subjob (with the tJavaFlex)

• Outside the tMemorizeRows subjob (with the tJava)

This Job uses five components:

• tFixedFlowInput: it contains rows of customer data such
  as IDs, names and ages of the customers.

• tSortRow: it sorts the rows according to the age
  data.

• tMemorizeRows: it temporarily memorizes a specific
  number of incoming data rows at any given time and indexes the memorized data rows.

• tJavaFlex: it compares the age values of the data
  memorized by the preceding component, counts the occurrences of different ages and displays
  these ages in the Run view.

• tJava: it displays the number of occurrences of
  different ages and the lowest age.

To replicate this scenario, proceed as follows:
