    Default String and IF statement

    	String user1 = JOptionPane.showInputDialog("Please enter the first player's name"); //Ask's for the user's name
    	String user2 = JOptionPane.showInputDialog("Please enter the second player's name"); //Ask's for the user's name
    	JOptionPane.showMessageDialog(null, user1 + " will go first! good luck!");

    I have this code and I wanted to make it so that if the user did not enter any name, it'd set the user1 to player1 and user2 to player2.

    I tried using an if statement something like

    if(user1 == " ")
    {
    }
    but not sure what to put within the if statement

    Use equals() instead of == to compare object values. See Common Java Mistakes
