java


public class MOD7Exercise1
{
    public static void main(String args[])
	{
		int palindrome[] = new int[25];
		int n=0;
		for(int i =0; i < 99999; i++)
		{
			String s1 = Integer.toString(i);
			StringBuilder sb=new StringBuilder(s1);
			if(s1.equals(sb.reverse().toString()))
			palindrome[i] = (int) (Math.random () * 99999) + 1;
			{
				palindrome[n++]=i;
				if(n == 25)
				{
					break;
				}
			}
		}
		for(int i=0; i<25; i++)
		{
			if(palindrome[i]%2==0)
			{
				System.out.println("Palindrome "+i+"="+palindrome[i]+ " is even");
			}
			else
			{
				System.out.println("Palindrome "+i+"="+palindrome[i]+ " is odd");
			}
		}
	}
}

here is the code. I am not getting 5 digit palindromes, but it is compiling and showing the odd and even. I can't think in what direction the start chasing. Road block in the brain!

I didn't get the code to indent. Sorry for that. I know it makes it harder to read. I think I was suppose to attach it not cut and paste. OOPS

However please post programming questions in the related programming forum next time, and when you post code put it inside code tags: Could you explain what this part of the code is supposed to do? java palindrome[i] = (int) (Math.random () * 99999) + 1; { palindrome[n++]=i; if(n == 25) { break; } }
