Java Programming for Complete Beginners - Java 16 - Step 29 - Java For Loop to Print Multiplication Table - Exercise Sol

The video tutorial covers the use of for loops in programming to print multiplication tables, numbers, and their squares. It demonstrates how to customize the table being printed using variables and how to print numbers in a sequence or in reverse. The tutorial also highlights the use of Jshell for immediate feedback, making it easier to experiment with code. The focus is on making programs more generic and reusable, with practical examples of incrementing and decrementing in loops.

What is the main advantage of using a variable to print multiplication tables?

• It makes the code more flexible and reusable.

• It allows printing multiple tables simultaneously.

• It increases the speed of execution.

• It makes the code shorter.

What is the initial condition for printing numbers from 1 to 10 in a for loop?

• Start with 1

• Start with 5

• Start with 0

• Start with 10

How do you print numbers in reverse order using a for loop?

• By incrementing the loop variable

• By using a nested loop

• By using a while loop

• By decrementing the loop variable

What change is needed to print every alternate number in a loop?

• Increment by 2

• Decrement by 1

• Increment by 1

• Decrement by 2

What happens when you decrement a loop variable by 2?

• It prints every alternate number.

• It prints every number.

• It prints every third number.

• It prints no numbers.

What is printed when you use 'I * I' in a loop?

• Squares of numbers

• Cubes of numbers

• Half of numbers

• Double of numbers

How can you print squares of the first 10 even numbers?

• Start the loop from 1 and increment by 1

• Start the loop from 2 and increment by 2

• Start the loop from 2 and increment by 1

• Start the loop from 1 and increment by 2

What is the starting point for printing squares of odd numbers?

• Start from 0

• Start from 2

• Start from 1

• Start from 10

What is a key benefit of using Jshell for programming?

• It provides immediate feedback.

• It requires less memory.

• It supports multiple languages.

• It is faster than other IDEs.

How can you modify a loop to print squares of the first 10 odd numbers?

• Start from 2 and increment by 2

• Start from 1 and increment by 2

• Start from 1 and increment by 1

• Start from 0 and increment by 1
