Learn Java from Scratch - A Beginner's Guide - Step 11 - Returning from a Java Method – Exercises

This video tutorial covers exercises on return values of methods. It includes two exercises: one to create a method that returns the sum of three numbers, and another to calculate the third angle of a triangle given two angles. The video emphasizes the importance of understanding methods, their inputs, outputs, and naming conventions. It concludes by highlighting the significance of methods in programming.

What is the main purpose of the exercises discussed in the video?

• To explore object-oriented programming

• To learn about data structures

• 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?

• Boolean

• String

• Integer

• Float

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

• Third number

• Second number

• First number

• Fourth number

What is the sum of angles in a triangle?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

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

• findThirdAngle

• calculateThirdAngle

• getThirdAngle

• determineThirdAngle

What should be considered when creating a method?

• The method's size

• The method's inputs, outputs, and name

• The method's speed

• The method's color

Why is it important to focus on writing great methods?

• Because they run faster

• Because they look good

• Because they have great names, the right inputs, and the right output

• Because they are easier to debug
