Capital Quiz JAVA

I need to write a capital quiz that looks like this: What's the capital of Colorado? (STOP to quit) Denver Right!

The information is on a file i imported. I need to do three class and I'm stuck on the second one. first one:

/**
 * Write a description of class State here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class State
{
    private String state; 
    private String abbreviation;
    private String capital;

    /**
     * Constructor for objects of class State
     */
    public State(String state, String abbreviation, String capital)
    {
        this.state = state;
        this.abbreviation = abbreviation; 
        this.capital = capital;
    }

    /**
     * Lab 7 for CS 1054
     * @return getmileage get method used
     */
    public String getState()
    {
        return state;
    }

    /**
     * Lab 7 for CS 1054
     * @return getmileage get method used
     */
    public String getAbbreviation()
    {
        return abbreviation;
    }
    /**
     * Lab 7 for CS 1054
     * @return getmileage get method used
     */
    public String getCapital()
    {
        return capital;
    }
    /**
    * Lab 6 for CS 1054
    * @param breed1 used
    */
    public void setState(String state1)
    {
        state = state1;
    }
    /**
    * Lab 6 for CS 1054
    * @param breed1 used
    */
    public void setAbbreviation(String abbreviation1)
    {
        abbreviation = abbreviation1;
    }
    /**
    * Lab 6 for CS 1054
    * @param breed1 used
    */
    public void setCapital(String capital1)
    {
        capital = capital1;
    }

    /**
     * Lab 6 for CS 1054
     * @return args agruments
     */
    public String toString()
    {
        return state + " (" + abbreviation + "), " 
            + capital;

    }

}
