This runs as is, but I'm looking for an alternative way to write it.

import java.util.Scanner;

public class StateBirdAndFlowerProgram {

    public static void main(String args[]) {

      // Begin Scanner for user input later on
      Scanner input = new Scanner( System.in );

       //Begin array of information
      String[][] states={
                        {"Alabama", "Flower: Camelia", "Bird: Northern flicker"},

Although this has answers, in general you really want to be more descriptive with what you want, and why. For instance, I'm not even sure if using an array is a requirement here? But if you're doing the same assignment that @h.j.k. linked, then it arguably is and my answer no longer applicable. \$\endgroup\$

I ran your code, and got this output:

Enter a state:
Bird: Flower: Peony
Flower: Bird: Northern cardinal

So, two things:

1) Your columns are in the wrong order or incorrectly labeled;
2) Your labels are duplicated. They are already in your data (which is unusual) so you could remove the labels from your print clause

                      System.out.println(states[row][column+2] + "\n");

In a more realistic situation though, very likely the labels would not be included along with the data

Better UI

Your user input is not very intuitive. Take this series of input:

Enter a state: 
Enter a state: 
Enter a state: 
Enter a state: 

This should be pretty easy for you to change the code to add a System.out.println("State not found: " + stateName) that's reached if the value entered is not found in the array.

Also consider adding this System.out.println("Enter a state: (or None to exit)"); as the way to exit your program is not obvious as it is.

Code comments

I'm not sure whether or not commenting every line of code was a requirement by your teacher, but most programmers would find it very excessive. In production code, you don't often see code comments (besides language-specific constructs like JavaDoc) as the code should speak for itself as to what it does. You normally only need to add comment if the reasoning behind a certain piece of code is not clear.

These are particularly excessive:

                     } // end if

                } // end for

           } // end else

      } // end while

 } // end main
} // end class

It is actually better in many cases not to declare variables until shortly before you need them. It makes code much more difficult to follow if you have to always look up and down to find variable declarations their usage. It also make it easier to keep variables in the correct scope.

  // Begin Scanner for user input later on
  Scanner input = new Scanner( System.in );

I'm sure others will find plenty of other things to critique and help you with your code, this is just a start.

  • \$\begingroup\$ that is supposed to be the output per the assignment \$\endgroup\$ Sep 29, 2015 at 22:16
  • \$\begingroup\$ If the closing parenthesis is far enough away that you feel like an "end XXX" comment is needed, that generally indicates that part of your function should be extracted into a sub-function. In this case, the can just be removed. \$\endgroup\$ Sep 30, 2015 at 14:29

Use Enum

Your data set is definitely something I would use an enum for, if not otherwise a csv.

A compact example on what that would look like:

enum States {
    AL("Alabama", "Camelia", "Northern Flicker"),
    NY("New York", "Rose", "Eastern Bluebird");

    private final String name;
    private final String flower;
    private final String bird;

    States(String name, String flower, String bird) {
        this.name = name;
        this.flower = flower;
        this.bird = bird;

    public String toString() {
        return name;

    public String initials() {
        return name();

    public String flower() {
        return flower;

    public String bird() {
        return bird;

an example on a way you would use the above:

import java.util.Scanner;

public class Tester {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        System.out.println("Enter a state's name or initials to look for:");
        String userSelection = input.nextLine();

        // search through the enum
        for (States state : States.values()) {
            if (userSelection.equalsIgnoreCase(state.toString())
            || userSelection.equalsIgnoreCase(state.initials())) {
                    state.toString() + "'s bird is the " + state.bird()
                    + " and their flower is: " + state.flower()

        /* You can extract the above into a method that returns true or false
           and  if false tells the user their entry was invalid/doesn't exist */
  • \$\begingroup\$ I was trying to think of a easy and nice way of checking for state name or initials myself. Nice example! \$\endgroup\$ Sep 30, 2015 at 11:58

Two things come to mind when I see something like this. Both boils down to encapsulation though. The first idea would be to make a State class that has a Flower, and a Bird property on it. You can then simply make a list of those States and filter appropriately.

static List<U_S_State> usStates;
static {
    usStates = new ArrayList<U_S_State>();
    usStates.add(new U_S_State("Alabama", "Flower: Camelia", "Bird: Northern flicker"));
//pre java 8, comparable needed on U_S_State
public void GetInfo1(String stateName){
    int index = usStates.indexOf(new U_S_State(stateName));
    if (index == -1){//not found

    U_S_State state = usStates.get(index);
    System.out.println("Bird: " + state.getStateBird());
    System.out.println("Flower: " + state.getStateFlower() + "\n");
//Using java8 stream comparable not needed on U_S_State
public void GetInfo2(String stateName){

    U_S_State state = usStates.stream()
            .filter(s->s.getStateName() == stateName)

    System.out.println("Bird: " + state.getStateBird());
    System.out.println("Flower: " + state.getStateFlower() + "\n");

public class U_S_State implements Comparable<U_S_State>{
    private final String stateFlower;
    private final String stateBird;
    private final String stateName;
    private String stateAbbreviation;

    public U_S_State(String stateName){
        this(stateName, "", "");
    public U_S_State(String stateName, String stateFlower, String stateBird) {
        this.stateFlower = stateFlower;
        this.stateBird = stateBird;
        this.stateName = stateName;

    public String getStateAbbreviation() {
        return stateAbbreviation;

    public void setStateAbbreviation(String stateAbbreviation) {
        this.stateAbbreviation = stateAbbreviation;

    public String getStateName() {
        return stateName;

    public String getStateBird() {
        return stateBird;

    public String getStateFlower() {
        return stateFlower;

    public int compareTo(U_S_State o) {
        return o.stateName.compareTo(this.stateName);

Mind you this probably isn't the best choice in names, (or even naming convention) but this does give you and idea of where to go. Making a class that can compare itself to others. We are only interested in comparing the states by their name. implementing Comparable<T> is important for list as it is how you will search for an item pre java 8. With java 8 you can use stream and lambda's. Handy if you understand them. That is my suggestion.
