Core Java Programming Course- "For" Loop in Java

The video tutorial explains the concept of a for loop, including its structure and usage for iterating code multiple times. It covers both incremental and decremental for loops, demonstrating how to set loop variables, limits, and steps. The tutorial also includes a practical example of using a for loop to find even numbers between 1 and 100 by applying a modulus operation.

What is the primary purpose of using a loop in programming?

• To debug code easily

• To make code run faster

• To repeat code multiple times

• To execute code only once

In a for loop, what does the initialization step do?

• It checks the loop condition

• It increments the loop variable

• It sets the starting value of the loop variable

• It ends the loop

How many times does the loop iterate in the example where the loop variable goes from 1 to 10?

• 12 times

• 9 times

• 10 times

• 11 times

What happens when the loop variable exceeds the upper limit in a for loop?

• The loop skips the next iteration

• The loop terminates

• The loop restarts

• The loop continues indefinitely

In a decremental for loop, what is the purpose of the step value?

• To keep the loop variable constant

• To increase the loop variable

• To decrease the loop variable

• To reset the loop variable

What is the condition for a number to be considered even in the given example?

• The number is greater than 50

• The number is divisible by 3

• The number has a remainder of 1 when divided by 2

• The number has a remainder of 0 when divided by 2

Which operation is used to determine if a number is even in the example program?

• Modulus

• Subtraction

• Addition

• Division
