6. Java Program to read Student Information and concatenate the same using delimiter.

/* 6. Write a Java program to read name, register number, date of birth, address, phone number a student.Concatenate these to frame a single content by delimiting each detail with a special symbol, pass it to a method which should separate and display the details of the student. Declare a class containing the following methods:
void getInformation() – to read student information. It should call concatenate(,,,,) by  passing relevant information. void concatenate(String name, string regNo, String dob, String  address, String phoneNo) to join the information to frame a single content. It should call extractInformation(…) by passing the concatenated information. void extractInformation(String joinedInfo) to extracted concatenated contents and to display the information. Declare another class to contain main () method which calls void
getInformation( ).
Sample output:
Student Name: Venkata Krishna
Register Number: BC171128
Date of Birth: 10/05/1996
Address: No. 5, First Cross, Nehru Nagar, Sagar.
Phone Number: 9900990099
Concatenated content:
Venkata Krishna%BC171128%10/05/1996%No. 5, First Cross, Nehru Nagar, Sagar.%9900990099
(Application: This is the way using which collection of information is communicated between
client and server in networked environment)*/
