Number Pattern Printing Programming

How to print number pattern programming

class NumberPattern
{
  public static void main(String[] args)
  {
  for (int i = 1; i <= 5; i++)
  {
for (int j = 1; j <= i; j++)
     {
  System.out.print(j+" ");
   }
System.out.println();
}
}
}

Output:

class NoPattern
{
public static void main(String[] args)
{
for (int i = 1; i <= 5; i++)
  {
   for (int j = 1; j <= i; j++)
   {
         if(j%2 == 0)
     {
System.out.print(0);
     }
else
{
System.out.print(1);
}
   }           
System.out.println();
}
}
}

Output:

class NumberPattern
{
public static void main(String[] args)
{
for (int i = 1; i <= 6; i++)
  {
    for (int j = 1; j <= i; j++)
     {
       System.out.print(j+" ");
     }
for (int j = i-1; j >= 1; j--)
  {
      System.out.print(j+" ");
    }
    System.out.println();
   }
}
}

Output:
