I am having problems with this program. I need to build a program that will demonstrate a loop that will print the following output by using two loops:.
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20

Here's what I have so far:

CODE


import java.util.Scanner;

public class TwoLines
{
   public static void main (String[ ] args)
   {
        Scanner keyboard = new Scanner(System.in);
                
        for (int number = 1; number <=10; number++)
        System.out.print("\t" + number);
        
        System.out.print("\n");
        
        for (int num = 11; num <= 20; num+=1)
        System.out.print("\t" + num);    
   }//end main method
}//end class



Thank you for your help!

where's your question? unsure.gif

but just to let you know:
CODE

for (int number = 1; number <=10; number++)
System.out.print(number+" ");
        
System.out.print("\n");
        
for (int num = 11; num <= 20; num++)
System.out.print(num+" ");


hope that helps smile.gif

Honestly, I don't know why I made that question because after looking at the last post made me realize that I knew how to do that. Anyways, thank you for opening my eyes and help me realize that I need to properly check my stuff before wasting your time with something I already knew. Still, hope other viewers receive help from this post. Thank you for the reply!

Actually, this I don't know. If I wanted to make a program perform this output:

1 2
3 4
5 6
7 8
9 10

How would I do it? I've been trying but this is as close as I can get:

CODE


import java.util.Scanner;

public class TwoLines
{
   public static void main (String[ ] args)
   {
        
        Scanner keyboard = new Scanner(System.in);
                
        for (int number = 1 && int num = 1; number <=5; number++)
        System.out.println("\t" + number);
        
   }//end main method
}//end class

Well, read in the numbers to an arraylist/array whatever you prefer.
Make a for loop to print out each number using the index based off of a %2 == 0 basis to print a new line
CODE

for(int i = 1; i<=numbers.length; i++)
{
     System.out.print(" " + numbers[i-1]);
     if(i %2 == 0)
          System.out.println();
}


Hope this helps!
