Here you go

public class Pattern
{
   public static void main(String[] args)
   {
      Scanner scanner = new Scanner(System.in);
      System.out.println("Enter the text ");
      String text = scanner.next();
      System.out.println("## Printing the pattern ##");
      for (int i = 0; i < text.length(); i++)
      {
         for (int j = 0; j <= i; j++)
         {
            System.out.print(text.charAt(j) + " ");
         }
         System.out.println();
      }

   }
}

{
   public static void main(String[] args)
   {
      int ascii = 65;
      for (int i = 1; i <= 5; i++)
      {
         for (int j = 1; j <= 5; j++)
         {
            if (i % 2 == 0)
            {
               System.out.print((char) (ascii + i - 1));
            } else
            {
               System.out.print((char) (ascii + i - 1 + 32));
            }
         }
         System.out.println();
      }

   }
}

   public static void main(String[] args)
   {
      String input = "INDIAN";
      System.out.println("** Printing the pattern... **");
      for (int i = 0; i <= 5; i++)
      {
         for (int j = 5; j > i; j--)
         {
            System.out.print(" ");
         }
         for (int k = 0; k <= i; k++)
         {
            System.out.print(input.charAt(k) + " ");
         }
         for (int l = i - 1; l >= 0; l--)
         {
            System.out.print(input.charAt(l) + " ");
