Create a form requiring a persons name, age and date of birth as input. The age should be provided using a NumberPicker and the date of birth via a DatePicker.Use a TextView to display a message such as Hello Joe your DoB is: 20/07/1970 and your age is 46.

I have coded..but struggling to print out the information.
