Learn Java from Scratch - A Beginner's Guide - Step 21 - Java Assignment Operator - Puzzles on Increment, Decrement, and

The video tutorial explores increment and decrement operators, demonstrating how to use 'number++' and 'number--' to adjust variable values. It introduces compound assignment operators like 'I += 2' to simplify code. The tutorial recaps previous lessons on variables and outlines the next steps, including printing a multiplication table.

What is the result of using 'number++' if the initial value of 'number' is 5?

• 5

• 4

• 7

• 6

Which operator would you use to decrease the value of a variable by one?

• --

• +=

• ++

• -=

What is the difference between '++number' and 'number++'?

• '++number' increments before use, 'number++' increments after use

• Both increment after use

• Both increment before use

• '++number' increments after use, 'number++' increments before use

How can you simplify the operation 'I = I + 2' using a compound assignment operator?

• I = 2 - I

• I += 2

• I = I - 2

• I = 2 + I

What is the result of 'I mod 2' if I is 5?

• 5

• 1

• 0

• 2
