title: How to use KeyListener
body: <p>I am currently trying to implement a keylistener in my program so that it does an action when I pressed an arrow key, the object in my program either moves left or right.</p>
  
  <p>Here is the moving method in my program</p>
  
  <pre><code>public void moveDirection(KeyEvent e)
      {
          int move = 0;
          int r = K.getRow();
          int c = K.getCol();
          if (e.getKeyCode() == 39) move = 1; //KeyEvent.VK_RIGHT
          if (e.getKeyCode() == 37) move = 2; //KeyEvent.VK_LEFT
          //if (e.getKeyCode() == KeyEvent.VK_DOWN) move = 3;
  
          switch (move)
          {
              case 1: if (inBound(r, c+1))
                          K.setLocation(r ,c+1); 
                      if (inBound(r, c-1) &amp;&amp; frame2[r][c-1] == K)
                          frame2[K.getRow()][K.getCol()-1] = null; 
                      break; //move right 39
              case 2: K.setLocation(K.getRow(), K.getCol()-1); break; //move left 37
              //case 3: b.setLocation(b.getRow()+1, b.getCol()); break; //move down
              default: return;
          }        
          processBlockList();
      }
  </code></pre>
  
  <p>I am wondering how the program is supposed to read in (KeyEvent) e. I cannot really type in an arrowkey....</p>
  
  <p>Please help! </p>
  
  <p>edit: I also need to know what I need to add to my code so that my program waits about 700 milliseconds for a keyinput before moving on to another method</p>
