Hello I need to pass the unit test the condition is to generate Integers in range from arg0 to arg2 . here is my attempt to solved 
@Override
			public IntegerGenerator createIntegerGenerator(int arg0, int arg1) {

			IntegerGenerator generator = new IntegerGenerator() {

					@Override
					public Integer getNext() {
						int i = arg0;
						for (; i < arg1; i++) {
						}
						return i;
					}
				};
				return generator;
			}
but it faille 
Expected [1,2,3,4,5,6,7,8,9,10,null]
but was [10,10,10,10,10,10,10,10,10]
maybe somebody could suggest how to solve this issue?
