title: How to use key fields with Java Arrays?
body: <p>I'm trying to use a key field with my array with Java but I'm confused on where to begin. My program is supposed to be that the user enters a name which would be the unique identifier and all this information would show up relating to the name kind of a mini Google. I have two classes, one is my abstract class and my other would be my main method class. If anyone could help me that would be great and very much appericated. </p>
  
  <p>Here is my class.</p>
  
  <pre><code>import java.util.HashMap;
  public class DataBase {
  
  private  String name;
  private  int year;
  private  String status;
  private  String habitat;
  private  String lifespan;
  
  public DataBase() {
  }
  
  HashMap list=new HashMap();
  public DataBase(String name, int year, String status, String habitat, String lifespan) {
      this.name = name;
      this.year = year;
      this.status = status;
      this.habitat = habitat;
      this.lifespan = lifespan;
  }
  
  
  public  String getName() {
      return name;
  }
  
  public  void setName(String name) {
      this.name = name;
  }
  
  public  int getYear() {
      return year;
  }
  
  public  void setYear(int year) {
      this.year = year;
  }
  
  public  String getStatus() {
      return status;
  }
  
  public  void setStatus(String status) {
      this.status = status;
  }
  
  
   public  String getHabitat() {
      return habitat;
  }
  
  public  void setHabitat(String habitat) {
      this.habitat = habitat;
     }
  
  
   public  String getLifeSpan() {
      return lifespan;
  }
  
  public  void setLifeSpan(String lifespan) {
     this.lifespan = lifespan;
  }
  
  
      public String toString()
  {
      String result = "";
      result += "\nName: "+ getName() + "\nYear: "+getYear()+ "\nStatus: "+getStatus()+ "\nHabitat: "+getHabitat()+"\nLifeSpan: "+getLifeSpan();
      return result;
  }
  
  }

  <p><strong>UPDATE:</strong></p>
  
  <p>I can print out both the name and the information but I don't know how to connect the two together.</p>
