Question
package test3;public class Test3 { // DO NOT write a main method public static String getUserName (String firstName, String lastName) { // return the user name as LastName, FirstName e.g. Smith, John } … } }
Solution
Sure, here is the implementation of the getUserName method in the Test3 class:
package test3;
public class Test3 {
// DO NOT write a main method
public static String getUserName (String firstName, String lastName) {
// return the user name as LastName, FirstName e.g. Smith, John
return lastName + ", " + firstName;
}
//...
}
This method takes two parameters, firstName and lastName, and returns a String in the format "LastName, FirstName". The + operator is used to concatenate the strings.
