Must-do problems: Conditional Statements

120 min · Beginner

Back to syllabus (Conditional Statements)

These are the classic decision problems every Java beginner should be able to solve with conditions alone, no loops. Work from Easy to Hard, run your program on every test, and open a hint only when you are stuck.

What you will learn

Turn a word problem into the right if, else-if, nested if or switch
Order conditions so the special cases are tested first
Handle boundaries, ties, negatives and invalid input
Pick long or double where int is not enough
