Thread: Printing a Combination

There are nine empty spaces. Each one of them can be filled with either a 0, 1 or 2. The output should be something like:
000000000
000000001
000000002
000000010
000000011
000000012
000000020
000000021
000000022
000000100
000000101
000000102
000000110
000000111
000000112
000000120
000000121
000000122
000000200
000000201
000000202
000000210

Here is the code that I have used:

public class casesalgo {
	public static void main(String args[])
	{
		for(int a=0;a<3;a++)
		{
			for(int b=0;b<3;b++)
			{
				for(int c=0;c<3;c++)
				{
					for(int d=0;d<3;d++)
					{
						for(int e=0;e<3;e++)
						{
							for(int f=0;f<3;f++)
							{
								for(int g=0;g<3;g++)
								{
									for(int h=0;h<3;h++)
									{
										for(int i=0;i<3;i++)
										{
											System.out.println(""+a+b+c+d+e+f+g+h+i);
										}
									}
								}
							}
						}
					}
				}
			}
		}
	}
}

The problem is that I am getting some blank lines in the output which I do not want. Why are they appearing and how do I get rid of them?

I am getting some blank lines

Can you post the output from the program that shows the blank lines.

Your code works fine on my PC. The problem might be caused by other reason.
