Print binary tree pattern in Java

To print a binary pattern in java is simple thing. its same like printing stars the only logic changes is here we have to print 1 or 0 instead of star. and thats also very easy. if we observe when (i+j%2==0) that time we have to print 1 else 0.

public class pattern2 {
 public static void main(String[] args) {



  for(int i=0;i<=4;i++)
  {
   for(int j=0;j<=i;j++)
   {
    if((i+j)%2==0)
    {
     System.out.print(1);
    }
    else
    {
     System.out.print(0);
    }
   }
   System.out.println();
  }
 }
}

Output:-
1
01
101
0101
10101
