1 It imports the Scanner class to facilitate user input.
2 In the main method:
• It creates a Scanner object sc to read input from the standard input stream (System.in).
• It uses sc.nextLine() to read a line of input as a String and stores it in the name variable.
• It uses sc.next().charAt(0) to read the next token (word) as a String and then extracts the first character of
that string as a char, storing it in the gender variable.
• It uses sc.nextInt() to read the next token as an int and stores it in the age variable.
• It uses sc.nextDouble() to read the next token as a double and stores it in the cgpa variable.

3 After reading all the values, it prints them to the console to verify that the input was correctly obtained.
