#Java #nested #loops

[BroCodez]

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

// nested loops = a loop inside of a loop

Scanner scanner = new Scanner(System.in);
int rows;
int columns;
String symbol = "";

System.out.println("Enter # of rows: ");
rows = scanner.nextInt();
System.out.println("Enter # of columns: ");
columns = scanner.nextInt();
System.out.println("Enter symbol to use: ");
symbol = scanner.next();

for(int i=1; i<=rows; i++) {
System.out.println();
for(int j=1; j<=columns;j++) {

}
}
}

I am having trouble understanding nested loops so I will watch this video on repeat until I understand.

One of the best sample codes I've seen for this series. That's some cool logic you used.

Great video. A clearer illustration of nested loops is a mechanical clock. The second hand ticks every second. The minute ticks every minute or every 60 ticks or 1 loop of the second hand. The same for the hour hand.

A little modification I would suggest is to put the println() to the end instead of the start of the inner loop.

for (int i = 1; i <= rows; i++) {
for (int j = 1; j <= cols; j++) {
System.out.print(symbol);
}
System.out.println(); // display the next row
}

python equivalent

for i in range (rows):
for j in range(cols):
print(symbol, end='')
print()

[rafikismayilov]

I do follow and watch your tutorials. Perfect and simple explanation. Thank you Bro !!!

[JuliHoffman]

This actually made sense! Thank you!!!

This is the best Java tutorial for beginners, so you can learn Java and English in one hit. Please keep going! I vote for Java advance tutorial. Thanks a lot Bro

[zhyakoxalid]

Thank you so much. I don't really understand how the nested loop works, I want to fully understand how the program creates rows and columns. by the next time I see my comment, this should be different.

Thanks bro

I bought udemy course and got bored now I am watching the same course from you thx bro

Why was the System.out.println(); in the for loop block so necessary that it's changing the whole output?

[nutkimheng]

This video is very useful! Thank you for make this video bro😃😃😃

[dunnodendedenish]

whats ythe difference between nextLine() and just next (). You have used both for strings?

[cristiangarciaperez]

quick question, how does it know to print the rows horizontally and the columns vertically?

[rylieRylie-ww]

question why this time you do not need to use println() to clear out the next int still bit confused about
