    <p>I'm a beginner with Java, and I've been making test code to apply some of the concepts I read about. So, I wanted to create a class to describe playing cards. The card class contains fields describing both suite and value (1 - 13 for all 4 suites). This class was very simple to create, as you can see --</p> <pre><code>public class Card { private String suite; private int cardValue; Card(String s, int cV){ this.suite = s; this.cardValue = cV; } public String getSuite(){ return this.suite; } public int getCardValue(){ return this.cardValue; } } </code></pre> <p>I made another class to test this class, as well as add 52 cards to an array (I have another class that will deal with a 52 card deck, but that's not important in the context of my question here). This class, called <code>CardTest</code>, contains the main method. I created a for loop that appends everything to the deck array, however my problems occur when I want to loop through the deck and print out card values (suite and value). I receive a NullPointException error. Here is the cardTest class: </p> <pre><code>public class CardTest { public static void main(String[] args){ Card[] temp = new Card[52]; for (int i = 0; i &lt;12; i++){ temp[i] = new Card("Spade", i + 1); temp[i+13] = new Card("Club", i + 1); temp[i+26] = new Card("Diamond", i + 1); temp[i +39] = new Card("Heart", i + 1); } for (int i = 0; i &lt; 52; i++){ System.out.println(temp[i].getSuite()); } } } </code></pre> <p>I tried to search for issues regarding this type of error, but the only thing I've gathered is that there is an issue with the Card objects being set to a default "null" value, which yields the error on the method call. </p>

    1. COAre you missing something? The second `for` loop is empty, and what you have is fine.

    2. COYeah, I just fixed that because I copied from IDE in-between edits without double checking

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
