Android Development for Beginners : Practice Set 2 Email Directory Example

MainActivity.java

        String firstName = "Lyla";
        String lastName = "Fujiwara";
        String contactInfo = firstName + " " + lastName;
        contactInfo = "<" + lastName + "." + firstName + "@justjava.com>";
        display(contactInfo);

Maybe
String firstName = "Lyla";
String lastName = "Fujiwara";
String fullName = firstName + " " + lastName;
String contactInfo = "<" + lastName + "." + firstName + "@justjava.com>";
display(fullName + contactInfo);

This worked for me :

    String firstName = "Lyla ";  
    String lastName = "Fujiwara";
    String contactInfo = firstName +  lastName +  " <" + lastName + "." + firstName + "@justjava.com>";
    display(contactInfo);

• I merged the 3rd line with the 4th line and removed the double quotes in the third line
• I also added a space to the string of the first name, to create a space between the first and last name
