    <p>I'm using JOptionPane in my code and i have this block:</p> <pre><code>Object[] move = { "Up", "Down" }; Object moveValue = JOptionPane.showInputDialog(null, "Where do you want to move?", "Input", JOptionPane.INFORMATION_MESSAGE, null, move, move[0]); </code></pre> <p>I'm using this above block multiple times and I was thinking, is there a way to give </p> <pre><code>Object[] move; </code></pre> <p>new values. When I try it like</p> <pre><code>Object[] move = { "Up", "Down", "Left" }; </code></pre> <p>it says <code>"Duplicate local variable move"</code> and when I try</p> <pre><code>move = { "Up", "Down", "Left" }; </code></pre> <p>it gives error <code>"Array constants can only be used in initializers"</code>.</p> <p>So is there a way for me to use my variable "move" multiple times?</p> <p>EDIT:</p> <p>Bigger part of the code is</p> <pre><code> while (true) { switch(hero.getPos()) { case 1: Object[] move = { "Up", "Down" }; Object moveValue = JOptionPane.showInputDialog(null, "Where do you want to move?", "Input", JOptionPane.INFORMATION_MESSAGE, null, move, move[0]); move = null; switch ((String) moveValue) { case "Üles": hero.setPos(hero.getPos() + 1); break; case "Paremale": hero.setPos(hero.getPos() + 5); break; } break; case 2: System.out.println("Draakon!!!!"); dragon = new Dragon(1); fight = new Fight(hero, dragon); break; case 3: System.out.println("hallo!"); move = { "Up", "Right", "Left" }; </code></pre> <p>So i have "move" defined on 4th row and also on the last one. Last one gives the error.</p>

    1. COare you reusing the above code inside the same methode? Is the declaration of `move` inside the methode as well?

    2. CO`Object[] move = { "Up", "Down", "Left" };` should be valid, are you sure you didn't leave another declaration of `move` somewhere in the code? Try renaming it to something else and see what happens.

A row detail

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.
