Java Programming for Complete Beginners - Java 16 - Step 04 - Java For Loop - Exercise - Print a Number Triangle

The video tutorial guides viewers through creating a method to print a number triangle using nested loops. It starts with an introduction to the exercise, followed by implementing a basic for loop. The tutorial then explains how to use a loop within a loop to achieve the desired output. Debugging techniques are discussed to ensure the code functions correctly. The video concludes with a recommendation to explore the code further using debugging tools.

What is the primary task described in the video?

• To calculate the factorial of a number

• To create a multiplication table

• To print a number triangle

• To sort a list of numbers

What is the purpose of the initial for loop?

• To find the maximum number

• To calculate the sum of numbers

• To print numbers in a single line

• To print numbers in reverse order

How does the nested loop contribute to the solution?

• It helps in sorting the numbers

• It prints the entire number triangle

• It reverses the order of numbers

• It calculates the average of numbers

What is the role of the variable 'J' in the nested loop?

• It calculates the sum of numbers

• It controls the inner loop

• It determines the number of spaces

• It controls the outer loop

What was the issue with the initial nested loop output?

• It printed numbers in a single line

• It printed duplicate numbers

• It printed numbers without spaces

• It printed numbers in reverse order

How was the issue of printing duplicates resolved?

• By using a different data type

• By adding a break statement

• By printing the value of 'J'

• By changing the loop condition

What debugging technique was suggested at the end?

• Using a debugger to step through the code

• Using a different programming language

• Rewriting the entire code

• Using print statements
