1. There are a few students in the class.
There are not very many students in the class.
There are few students in the class.
Literally, this could be interpreted to mean the class is full of people, but not many of them are "students" - meaning not many of them actually have an interest in learning.
2.There is a little water in the jar.
There is little water in the jar.
In this case, the two sentences say the same thing. However, in the context of a paragraph, "there is a little water in the jar" sounds like an answer to someone's question - "How much water is left?", while "there is litte water in the jar" indicates that someone is making a pronouncement: "There is little water in the jar, so we must begin rationing it."
