Lesson 2 Practice — Number Analyzer

Create:

ZCL_ABAP_L02_PRACTICE_###

Requirements

Create an internal table containing at least 10 integers.

Write methods:

SUM
COUNT_EVEN
COUNT_GREATER_THAN
MINIMUM
MAXIMUM

COUNT_GREATER_THAN must import a threshold.

Your main method should:

1. build the internal table;
2. print each value with its index;
3. call every method;
4. print the results.

Additional task

Create a second internal table of circle radii and call a CIRCLE_AREA method for each radius.

Reasoning

1. Why is this data not persistent?
2. When is sy-tabix meaningful?
3. What can happen if numbers[ 50 ] is evaluated when no such line exists?
4. Why might a method be clearer than putting every calculation in main?
5. When is VALUE preferable to repeated APPEND statements?

Checklist

• Explicit internal table type/key.
• At least one VALUE construction.
• At least one LOOP AT.
• At least one WHERE or conditional filter.
• Methods use IMPORTING/RETURNING appropriately.
• No database access.
