System out println  First Name      firstname   System out println  Last Name      lastname     or  System out println String format  First Name   s   firstname    System out println String format  Last Name   s   lastname

You can create Class Person with fields firstName and lastName and define method toString    Here I created a util method which returns String presentation of a Person object   This is a sample  Main  public class Main        public static void main String   args            Person person   generatePerson            String personStr   personToString person           System out println personStr              private static Person generatePerson             String firstName    firstName    generateFirstName            String lastName    lastName    generateLastName          return new Person firstName  lastName                      You can even put this method into a separate util class             private static String personToString Person person            return person getFirstName       n    person getLastName              Person  public class Person        private String firstName      private String lastName         getters  setters  constructors      I prefer a separate util method to toString    because toString   is used for debug   https   stackoverflow com a 3615741 4587961  I had experience writing programs with many outputs  HTML UI  excel or txt file  console  They may need different object presentation  so I created a util class which builds a String depending on the output
