Thread: Help WordSearchProject

I keep getting the nullPointerException for this. It's a word search program. I'm aware that its one of the ugliest programs you will ever see, but I just need it to work. Every class name is underlined in yellow and the entire 2d Object array is underlined in yellow. Heres the error message in console:
Exception in thread "main" java.lang.NullPointerException
at ProjGui.<init>(ProjGui.java:49)
at WordsForSearch.<init>(WordsForSearch.java:18)
at ProjGui.main(ProjGui.java:91)

and heres the program. It has two classes

that's the thing it shouldn't be null

Well I'm fairly sure it has to do with the Object[][] not being declared earlier, but I don't know how considering windowbuilder gave it no name and it is exclusively for the jtable in the gui.
