Java: Setting one ImageIcon equal to another

I'm trying to make xpic equal to vpic just like in the example below. When I try to compile this code I get the error : "The local variable xpic may not have been initialized"

ImageIcon xpic;
ImageIcon vpic;

    vpic = new ImageIcon(getClass().getResource("Images/picture.png"));     
    vpic = xpic;
Solution

  • I think that you have a typo because your code sets the vpic variable's reference, and then completely ignores what you set it to, and tries to set it to xpic (which is likely a null reference).

    In essence, what you're doing is equivalent to this:

    // both Strings are null
String str1; 
String str2; 

// assign a String object to str1:
str1 = "Hello";

// but then ignore and in fact discard the String object, and 
// re-set str1 to null by assigning it str2
str1 = str2; //????

    You might want to change

    vpic = new ImageIcon(getClass().getResource("Images/picture.png"));     
vpic = xpic;

    to 

    vpic = new ImageIcon(getClass().getResource("Images/picture.png"));     
xpic = vpic;
