Practice 1: Write code that reads in a user\'s first and last name. Create a username for the user. The user name is: the first initial of their first name, the first six characters of their last name (or the whole last name if shorter than six chars long), and a two-digit random number. For example, my user name might be jmaster53. A user name for Jane Doe might be jdoe81.
Solution
public class FirstNameLastName { public static void main(String[] args) { String input; // The input line entered by the user. int space; // The location of the space in the input. String firstName; // The first name, extracted from the input. String lastName; // The last name, extracted from the input. System.out.println(); System.out.println(\"Please enter your first name and last name, separated by a space.\"); System.out.print(\"? \"); input = TextIO.getln(); space = input.indexOf(\' \'); firstName = input.substring(0, space); lastName = input.substring(space+1); System.out.println(\"Your first name is \" + firstName + \", which has \" + firstName.length() + \" characters.\"); System.out.println(\"Your last name is \" + lastName + \", which has \" + lastName.length() + \" characters.\"); System.out.println(\"Your initials are \" + firstName.charAt(0) + lastName.charAt(0)); } } ** * This program reads the user\'s first name and last name, * separated by a space. It then prints the user\'s first and * last names separately, along with the number of characters * in each name. It also prints the user\'s initials. Note that * this program will crash if the user\'s input does not contain * a space. */

Practice 1- Write code that reads in a user-'s first and last name- Cr.docx
1. Practice 1: Write code that reads in a user's first and last name. Create a username for the user.
The user name is: the first initial of their first name, the first six characters of their last name (or
the whole last name if shorter than six chars long), and a two-digit random number. For example,
my user name might be jmaster53. A user name for Jane Doe might be jdoe81.
Solution
public class FirstNameLastName { public static void main(String[] args) { String input; // The
input line entered by the user. int space; // The location of the space in the input. String
firstName; // The first name, extracted from the input. String lastName; // The last name,
extracted from the input. System.out.println(); System.out.println("Please enter your first name
and last name, separated by a space."); System.out.print("? "); input = TextIO.getln(); space =
input.indexOf(' '); firstName = input.substring(0, space); lastName = input.substring(space+1);
System.out.println("Your first name is " + firstName + ", which has " + firstName.length() +
" characters."); System.out.println("Your last name is " + lastName + ", which has " +
lastName.length() + " characters."); System.out.println("Your initials are " +
firstName.charAt(0) + lastName.charAt(0)); } } ** * This program reads the user's first name
