Question

What will be the result of running the following code fragment? int year = 0; double rate = 5; double principal = 10000; double interest = 0; while (year < 10) { interest = (principal * year * rate) / 100; System.out.println("Interest " + interest); }

Answer 1

Answer:

This code fragment will run an infinite loop

Explanation:

This output: Interest 0.0 Will be displayed infinitely. The reason is because the variable year which is initially set to 0 is never updated and as such remains true because the condition is while(year<10). So at the first iteration the statement interest = (principal * year * rate) / 100; evaluates to 0 and this line of code System.out.println("Interest " + interest); prints Interest 0.0. At the next iteration the same evaluation and output takes place and on and on and on....... since the control variable is not changing.
