Post your code and we will help you correct it, but no one is just going to give it to you.

As you can see for each line, you have a start, then increase each element by 1 and when you reach 5, if you didn't insert 5 elements in the line start reducing.
5 4 3 2 1(start)
4 5(reached 5, will decrease until the line is filled) 4 3 2(start)
3 4 5(reached 5, will decrease until the line is filled) 4 3(start)
5 4 3 2 1(start)
4 5(reached 5, will decrease until the line is filled) 4 3 2(start)
3 4 5(reached 5, will decrease until the line is filled) 4 3(start)

public class LogicPuzzle1 {
public static void main (String [] args)
{
final int num = 5;
int ctr;
int ctr2;
int temp=0;
for(ctr=num;ctr>0;ctr--)
{
System.out.print(ctr);
if(ctr!=num)
{
temp=ctr;
if(temp==num)
{
for(ctr2=1;ctr2<num;ctr2++)
{
temp--;
System.out.print(temp);
}
}
else
{
for(ctr2=1;ctr2<num;ctr2++)
{
temp++;
System.out.print(temp);
}
}
}
else
{
for(ctr2=1;ctr2<num;ctr2++)
System.out.print(ctr-ctr2);
}
System.out.println();

There are many ways to implement this, so if it works don't worry about it. In my idea I was thinking of creating an array 5x5, and put the values in it before printing them. I think that it would have been simpler because with the array I could start putting things at the end of the array:
arr[0][4] = 1
arr[0][3] = 2 . . .
So instead of while inside the first for-loop, I would have the outside loop counting the line of the array, and the inside loop counting backwards and start putting the values at the end of the array.
arr[0][4] = 1
arr[0][3] = 2 . . .
