New to Java

Hi! i�m doing a program and i have to load a diccionary to my program. I load the word into an hashTable. I want to do another Hash with the anagrams of the words loaded from the file.
I tried to go over the dicionary hashTable and to each word compare all the words on it and test if they are anagrams. if they are i put them into a list. This seem to be very bad once o let my pc running the program for 15 minut and it didn't ended it and went to 76 celcium degrees. So i'm trying to do a function that allows me to pick a word and creat a list with the possible anagrams and compare the values in the list to see if thye exist into the dicionary hashTable but i 'm not able to do this. Can someone help me out telling me where can i start and what i nedd to do!
Thanks
