The document is an exam for an Introduction to Internet Programming course, consisting of two compulsory questions worth 10 marks each. The first question asks students to write a Java program to calculate the sum of a harmonic series given an interactive user input for n. The second question asks students to write a Java program to extract a portion of a character string starting from the nth character for a length of m, accepting both n and m through interactive user input.

n
The value of n should be given interactively-through the keyboard.
2. Write a program to extract a portion of a character string, and print the extract string. 10
