Example of what i did:

x x x \

Example of what i need:
\ x x \
x \ \ x
x \ \ x
\ x x \

What I have tried:

System.out.println("Please enter the length of the side: ");
             
             int side =kb.nextInt();
             for (int i = 1; i <= side; i++ ) 
		{
			for (int j = 1; j < i; j++ ) 
			{
				System.out.print("X ");
			}

The first diagonal has a variable x. The other diagonal will be 4-x where 4 is the length of the line.

I'm just guessing, but what you really need is this, isn't it:
\ x x /
x \ / x
x / \ x
/ x x \

And there is a simple way to do it, with just two loops and a couple of ifs.

Think about what you are doing: for each row you print, the column with the same number as the row should be a '/'.
And the column with the same number as the N minus the row number should be a '\', where N is the number of rows (minus one if you start with row and column zero).
All the other characters are 'X'.

So have a loop for each row, and a nested loop for each column in the row, and use an if ... else if ... else inside the loop to decide which character to print.

Try it on paper and you'll see what I mean.
