This seems likely to be a homework assignment.

You can refer to another student's work here http://www.experts-exchange.com/Programming/Languages/Java/New_to_Java/Q_22978447.html
for an example of prompting for input and accepting a String from the Scanner object.

If you review the String object, you'll find substring handling methods.

Checking for substring is a fairly simple task, as you can use the indexOf property of a String

http://java.sun.com/javase/6/docs/api/java/lang/String.html#indexOf(java.lang.String)

Returns:
    if the string argument occurs as a substring within this object, then the index of the first character of the first such substring is returned; if it does not occur as a substring, -1 is returned.
