Java Programming for Complete Beginners - Java 16 - Step 25 - Java Conditionals and If Statement - Exercise Solutions

The video tutorial covers three exercises using if statements in Java. The first exercise involves comparing sums of variables to demonstrate the use of if statements. The second exercise checks if three angles form a valid triangle, highlighting the importance of using comparison operators instead of assignment operators. The final exercise uses the modulus operator to determine if a number is even, explaining the logic behind even and odd numbers. The tutorial emphasizes proper formatting and understanding of operators in Java programming.

What is the result of the condition if A+B is greater than C+D when A=1, B=2, C=3, and D=1?

• The condition is false and the statement is not printed.

• The condition is true and the statement is printed.

• The condition is true but the statement is not printed.

• The condition is false but the statement is printed.

Which operator should be used to compare if the sum of angles in a triangle equals 180?

• Double equals (==)

• Single equals (=)

• Not equals (!=)

• Triple equals (===)

What is the correct way to adjust angle three to make the sum of angles equal 180?

• Increase angle three by 50

• Set angle three to 60

• Decrease angle three by 50

• Set angle three to 80

What is the remainder when an even number is divided by 2 using the modulus operator?

• 0

• 1

• It depends on the number

• 2

If a number is odd, what will be the result of number mod 2?

• 1

• It will cause an error

• 2

• 0

What is the purpose of using the modulus operator in checking if a number is even?

• To find the quotient of the division

• To find the remainder of the division

• To check if the number is negative

• To check if the number is positive

What will be covered in the next video after these exercises?

• Functions and methods

• Puzzles related to the if condition

• Loops and iterations

• Advanced if statements
