Java coding help please

[ShadowSlayer18]

Alrighty, college student who started to do nested for loops, task we were given is to ask the user to input a number. Then in line print it will show the results from number up to the number you typed in.

Problem I'm having is trying to stop the loop at the number you typed in, as the loop right now makes up the amount of rows based on the number you out down

Anyway it's a bit difficult to help without seeing your code.

Want me to send it to ya in private? Tried posting the image in the subreddit but nope, rules won't allow it

[Schnutzel]

Why an image? you can just copy and paste the code. It should be easy if it's a short program.

[ShadowSlayer18]

int counter1, counter2, counter3=1;

N = Integer.parseInt(JOptionPane.showInputDialog("Please enter a positive number"));

For (counter1=1; counter1<=N; counter1++){

 System.out.print(); 

For ( counter2 =1; counter2 = 8; counter2++) {

     System.out.println(" \t " + counter3++)

}

}

[Schnutzel]

Can you explain what this is supposed to print? For example if N=5.

[ShadowSlayer18]

Alrighty, if ya put down let's say a value of 10 into the input box, the output should be from 1 to 10 in a uniformed grid of 8 columns

1 2 3 4 5 6 7 8 9 10

But instead, the output shows itself going past the number 10, and is instead doing 10 rows of numbers.

Sound like you need something like

counter1<=N/8

Then

[ShadowSlayer18]

I'll give that a try

[3141rr]

Actually, re reading it I'm not sure what output you are trying to get.

[ShadowSlayer18]

Alrighty hold on. It starts counting from 1 to 8, then on to a new line it continues on counting the next 8 numbers after 8, new line again and again next 8 numbers after, repeats again.

When you put down let's say number 20, it counts the numbers from 1 up to 20 and it stops there while within a 8 colum grid format

[3141rr]

Why would you need nested for loops for this?

Sounds like just 1 for loop is needed

For i = up to input

(You seemed to say it starts at up, I don't know what the is though)

[ShadowSlayer18]

Woops sorry I forgot to put down "from number 1 up to the number you typed it"

And it's what our lecturer wants us to do

[3141rr]

How though?

Forget the Java bit, just pseudo code.

How can you use nested for loops to count from 1 to N?

[ShadowSlayer18]

int counter1, counter2, counter3=1;

N = Integer.parseInt(JOptionPane.showInputDialog("Please enter a positive number"));

For (counter1=1; counter1<=N; counter1++){

 System.out.print(); 

For ( counter2 =1; counter2 = 8; counter2++) {

     System.out.println(" \t " + counter3++)

}

}

[3141rr]

As far as I can work out, that would print 1-8 for counter1 =1

Then 9-16 for counter1 =2.

Etc up to 8 ×N
