Learn Java from Scratch - A Beginner's Guide - Step 25 - Java Conditionals and If Statement - Exercise Solutions

The video tutorial covers three exercises involving if statements in programming. The first exercise checks if the sum of two variables is greater than another sum. The second exercise verifies if three angles form a valid triangle, highlighting the importance of using comparison operators instead of assignment operators. The third exercise demonstrates how to determine if a number is even using the modulus operator. Each exercise is explained with examples and common errors are addressed.

What are the values assigned to variables A, B, C, and D in the first exercise?

Explain why the statement 'A + B is greater than C + D' did not print initially.

What is the correct way to check if the sum of three angles forms a valid triangle?

What mistake was made when checking if the angles of a triangle sum to 180?

Describe the importance of using the correct comparison operator in programming.

How can you determine if a number is even using the modulus operator?

What is the output when the number is 9 and you check if it is even?
