    Default using if statement on string System.getProperty("os.name") not working

    Hello,

    Several things of note:

    1) I'm very new to both coding and this forum

    2) I did a search for os.name in this forum and got nothing.

    Here's my code:
    if (System.getProperty("os.name") == "Mac OS" || System.getProperty("os.name") == "Mac OS X")
    {
    	NewItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_N, ActionEvent.META_MASK));
    	OpenItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_O, ActionEvent.META_MASK));
    	SaveItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_S, ActionEvent.META_MASK));
    	QuitItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, ActionEvent.META_MASK));
    }
    else
    {
    	NewItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_N, ActionEvent.CTRL_MASK));
    	OpenItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_O, ActionEvent.CTRL_MASK));
    	SaveItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_S, ActionEvent.CTRL_MASK));
    	QuitItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, ActionEvent.CTRL_MASK));
    }

    I did a
    System.out.println(System.getProperty("os.name");
    And it gives me Mac OS X, but it doesn't set the accelerator to meta, instead setting it to control.

    (NewItem, OpenItem, SaveItem, and QuitItem are all JMenuItems)

    Do not use == when comparing objects (unless you wish to compare the objects are the same references). Use the equals method (eg myString.equals(otherstring) )

    Your way of comparing strings is wrong
