The last pane on your screen is "Dbms Output". Click the green "+" sign in its toolbar, and then execute the BEGIN-END block again.
Upon going through the Oracle community forums, I learned that SQL Developer 17.x which I am using does not provide support to Oracle 10g.
Older version of the SQL Developer 4.x will support Oracle 10g and retrieve DBMS_OUTPUT buffer to display it on the screen.
Since I only had a small database set up for my homework and did not want to downgrade to an older SQL Developer, I upgraded to Oracle 11g XE and it worked. All input given to DBMS_OUTPUT.PUT_LINE() procedure now appears in the Dbms Output window.
