this is my source code:

import java.io.*;
public class lopezKrizar_Triangle{
public static void main (String[]args)throws IOException{
DataInputStream kriz=new DataInputStream (System.in);
int ctr;
int ctr2;
int num;


System.out.print ("Enter a Number: ");
num=Integer.parseInt (kriz.readLine());

for (ctr=0;ctr<=num;ctr++)
{
System.out.println();
for (ctr2=0;ctr2<ctr;ctr2++)
{
System.out.print("*");
}


}


}
}

and this is only the output of mine

I'm not really into Java, but since it's all just some simple loops, this should do the trick:

for(int i = 0; i <= 2*num - 1; i++)
{
	System.out.println();
	for(int j = 0; j < i; j++)
	{
        	System.out.print("*");

        	if(j >= 2*num - 1 - i)
			break;
	}
}
