If you really have no idea at all, then I cannot help you. You'd better ask your teacher or read your course book how to program in Java.

Ah, you know how to program.
Use a for statement to loop a n-number of times, where n is the length of the String. Print the String in the for-statement and then get the first character of the String and place it at the end of the String:
String s = "java";
for(...) {
print 's'
s = [substring of 's' from index 1 -> end] + [substring of 's' from index 0 -> 1]
}
Have a look at the String API docs:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html
especially at the substring(...) methods.
