Java Programming for Complete Beginners - Java 16 - Step 11 - Returning from a Java Method – Exercises

The video tutorial covers the concept of return values in methods, emphasizing their importance through two exercises. The first exercise involves creating a method to calculate the sum of three numbers, while the second focuses on finding the third angle of a triangle given two angles. The tutorial highlights the significance of methods in programming, stressing the need for clear method names and proper input-output handling.

What is the purpose of the exercises introduced in the video?

• To explore object-oriented programming

• To learn about data types

• To understand return values of methods

• To practice writing loops

What is the return type of the method that calculates the sum of three numbers?

• String

• Boolean

• Integer

• Float

Which of the following is NOT a parameter in the method to calculate the sum of three numbers?

• First number

• Second number

• Third number

• Fourth number

What is the maximum sum of angles in a triangle?

• 180 degrees

• 90 degrees

• 360 degrees

• 270 degrees

What is the name of the method used to calculate the third angle in a triangle?

• calculateThirdAngle

• findThirdAngle

• computeThirdAngle

• getThirdAngle

Why is it important to have a clear method name?

• To make the code run faster

• To avoid syntax errors

• To understand the method's purpose without looking at the logic

• To reduce the number of parameters

What percentage of programming time is typically spent writing code inside methods?

• 100%

• 50%

• 75%
