Q2.

  1.  write a Java program to encode a name by creating an array of integers.
  2. Write Java method called encodeName that takes a name as a string (without spacing and all lower case) and returns an array of integers of the same size as name whose elements are the number in the alphabet of the corresponding character in name (starting from zero). For example, calling this method with name = “aabed” it should return [0, 0, 1, 4, 3].
  3. Write a printArray method that prints all the elements of an array of integers in one line.
  • Write a main method that calls encodeName and printArray methods to print the array corresponding to your name.
