ICSE 2017 Computer Applications Question Paper for Class 10

About this paper

This is the ICSE Class 10 Computer Applications (Theory) paper for 2017, paper code T17 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 inheritance, operators, data type sizes, character and String methods, Math functions, loop conversion, nested loops and the Scanner methods next() and nextLine(). In Section B candidates write Java programs for any four of six questions: an ElectricBill class with a slab tariff and surcharge, spy numbers, a series and pattern menu, array largest, smallest and sum, overloading check(), and sorting forty words by selection sort. This copy has the questions only.

Questions from this paper

1. What is inheritance?
2. Why is an object called an instance of a class?
3. What is the difference between the Scanner class functions next() and nextLine()?
4. Write a program to accept a number and check whether it is a spy number, that is, one whose sum of digits equals the product of its digits (for example, 1124).
5. Write a program to input integer elements into an array of size 20 and display the largest number, the smallest number and the sum of all the elements.
6. Write a program to input forty words in an array, arrange them in descending order of alphabets using the selection sort technique, and print the sorted array.
