Question

How come when i put //private String namespace = “###Name:”+name+” ###”; and system.out.println(namespace) it comes out null?

I am suppose to create a tagmaker program, but I am stuck at how to line up the # on the right side.

/*################################################
###               ANNUAL CONFERENCE            ###
############################################### #
###Name:Simon                             ###
###                                           ###
############################################### #
###Organization:NBA             ###
###                                             ###
################################################*/

How do I line them up for any given name that I set it to?
I am suppose to Set the Name, Set the organization, Print tag with the name and organization, Clear the name and organization, and Print a blank tag.

—————-UPDATE 4:09AM—————————-
I am just going to model my code after this:

public class Divers {
    public static void main(String args[]){
      String format = "|%1$-10s|%2$-10s|%3$-20s|\n";
      System.out.format(format, "FirstName", "Init.", "LastName");
      System.out.format(format, "Real", "", "Gagnon");
      System.out.format(format, "John", "D", "Doe");

      String ex[] = { "John", "F.", "Kennedy" };

      System.out.format(String.format(format, (Object[])ex));
    }
   }

but can someone show me how i can do it the other way? just for learning purposes

public class AddressBookTester {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
TagMaker test =  new TagMaker("Simon", "NBA");

test.printlL();

    }

}

public class TagMaker {

private String name;
private String organization;
private String l = "################################################";
private String annual= "###               ANNUAL CONFERENCE            ###";
//private String namespace = "###Name:"+name+"                ###";
private String l2= "###                                             ###";
//private String organizationspace= "###Organization:"+organization+"###";
TagMaker (){

}

TagMaker (String tempName, String tempOrg){
name = tempName;
organization = tempOrg;

}
    void setname(String tempName){
        name = tempName;
    }

    String getname(){
        return name;
    }

    void setorganization(String tempOrg)
    {
            organization = tempOrg;
    }

    String getorganization(){
        return organization;
    }


    void printlL(){
        System.out.println(l);
        System.out.println(annual);
        System.out.println(l);
        System.out.println("###Name:"+name+"                             ###");
        System.out.println(l2);
        System.out.println(l);
        System.out.println("###Organization:"+organization+"             ###");
        System.out.println(l2);
        System.out.println(l);

    }
    }

Answer 1

You need to set a constant for the Maximum width (in characters) of your output. Then you can do some simple arithmetic to work out how many spaces/characters etc. you need to properly format your output.

Say if max_width = 60.

Here’s a header:
############################################################ _{(the full 60)}

The you work out the indents and things based on the length in chars of the strings you’re outputting.

e.g. If you want to print Name: Simon get the length of this and subtract from max_length, etc. etc.

HTH.
