    Default Sorting question

    I'm trying to write a program that generates 100 random number, prints them, then sorts them, then prints out the sorted list with ten numbers in each line. I cannot figure out what is wrong with my code. Anyone have any ideas? A detailed explanation would be awesome as I am new to this. This is what I have so far.

    public class Main {
     
    	public static void main(String[]Args)
    	{
    		int [] b;
    		b = new int[100];
    		loadArray(b);
    		printArray(b);
    		Sort(b); 
    		printArray(b);
    	}
     
    	public static void loadArray(int[] b) {
    		for(int i = 0; i < b.length; i++){
    			b[i]= (int)((Math.random())*100)+1;{
     
    			}
    		}
     
    	}
     
    	public static void printArray(int[] b){
    		System.out.println();
    		for(int i = 0; i < b.length; i++){
    			System.out.print(b[i]);
    			if((i + 1)%10 == 0)
    				System.out.println();
    		}
    	}
     
    	public static void Sort(int [] b)
    	{
    		int Temp = 0;
    		for (int i = 0; i < b.length-1; i++)
    		{
    			for (int j = i + 1; j < b.length; j++)
    			{
    				if (b[i]> b[j])
    					{
    					Temp = b[i];
    					b[i] = b[j];
    					b[j] = Temp;
    					}
    			}
    			}
     
    		}
     
     
    }

    And here is an example of what it prints out right now.

    84858688909191919393
    9393969696979899100100

    As you can see all of the lines have more than 10 numbers in them except for the first line of the sorted list, which is also the only line that is sorted. Any help would be appreciated, thanks.

    I know, I'm sorry. I usually can figure it out faster if I get more advice though.

    The least you can do is provide links between crossposts, that way we know what other help you've already received. There's no point in answering your question if you've already figured it out on another forum.

    It might be faster for you, but it's a huge waste of our time, which is pretty rude considering we're doing this in our spare time for free.

    I'm sorry, I'll be more courteous next time.

    I've found out that the list is sorted, there are just no spaces between the double digit numbers. I can't think of any way to add them.

    Hello.
    You are not printing the numbers properly. How can someone like us know whether a number is 1-digit or 2-digit? Even though you are printing ten numbers in a row try to put some space in between every two numbers.
    Then we can say if the numbers are really sorted or not. May be its sorted but we can't differentiate because of them being adjacent to each other.
    If the problem is still not solved let us know.

    Syed.

    Really?

    You can write the code to print a number but you have no idea how to print a space after that number.

    He already received this advice on two other forums. Seems he got the answer and is long gone.
