if you are looking for answers, you can usually find the exact question by pasting part of the question in quotation marks in google. for example if the question is:
Farmer Dawson has ten cows. How many cows would he have if you removed half? Remember to express answer as a function.
could be found with
"how many cows would he have if you removed half"
"you removed half? Remember to express answer as a function."
putting something in quotation marks on google makes google search for the exact text you typed in between the marks, no exceptions. if you do find your question, make sure the answer is in Java, not javascript, not python, not c(++), etc.
