ICSE 2015 Computer Applications Question Paper for Class 10

About this paper

This is the ICSE Class 10 Computer Applications (Theory) paper for 2015, paper code T15 861. It is a two-hour paper with fifteen minutes of reading time, and its two sections carry 40 and 60 marks. Section A has three compulsory questions of two-mark parts on default values, OOP principles, identifiers, literals, wrapper classes, constructors, exception handling, access specifiers and output prediction. In Section B candidates write Java programs for any four of six questions: a ParkingLot billing class, two pattern programs, student remarks from average marks, overloading Joystring(), sorting twenty names by bubble sort, and a menu for factors or factorial. This copy has the questions only.

5. Write a program to input twenty names in an array and arrange them in descending order of alphabets using the bubble sort technique.
6. Using the switch statement, write a menu-driven program to display all the factors of a number (including 1 and excluding the number itself) or the factorial of a number.
