    Question 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?

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