Craps Game Java

I am supposed to be making a game of craps in java, but I have a problem. You see, technically the game is finished, but it will not say if you loose the game or not even if you do. It will only continue to roll til you win. I tried a couple workarounds but it only seems to trap it in an infinite loop. Here is my code as follows:

/* Class:        CS1301
* Section:       8
* Term:          Fall 2015
* Name:          Matthew Woolridge
* Instructor:    Mr. Robert Thorsen
* Assignment:    Assignment 8
* Program:       4
* ProgramName:   CrapsGame
* Purpose:       Allows the user to play a game of craps
* Operation:     The information is statically instantiated in the code and
*                the data is output to the screen.
* Input(s):      The input is the next roll
* Output(s):     The output is correct or incorrect and points
* Methodology:   The program uses booleans, integers, loops and methods to play a game of craps
*
