Solved Java programs for ICSE and ISC
Programming carries the largest share of marks in both ICSE Computer Applications and ISC Computer Science. This collection of solved Java programs covers the patterns that appear in board papers year after year: special numbers (Armstrong, Niven, Kaprekar, Spy and more), series, patterns, string handling, arrays, searching and sorting, matrices, recursion, inheritance and data structures.
Every program is complete, runs in BlueJ and shows sample output. Read the logic, type the program yourself, and then change it slightly — for example, count words that end with a vowel instead of starting with one. That habit prepares you for the variations examiners like to set.
