/**
 * Demonstrate capabilities of String class
 * Use your knowledge of types and method
 * to finish the lab.  There are parts missing 
 * and  errors as well. So i.e.think what do you 
 * need to add to have certain part of print 
 * statement to work and so on.
 * Also, all of the answers can be tested via
 * print statements.  Only last one is finishing
 * the expression.

System.out.println("length of m is: " +l);

//What does this do?
System.out.println("concat is: " r);

//What does this print and what index is the function using?
System.out.println("character is: " +s.charAt(6));

//Make String m all upper case

//What is the index of r for String s?

//What is difference between "==" and "equals"?

//m and p are same objects? How about m and q?

//Does m equal p? Does m equal s?

//if you have an integer and want to return string representation
//of the value, How will you do so?
int value = 9;
//Hint: finish the missing expression to answer the question
//Also remember how to use a static method.
//String valToStr = 
System.out.println("value of valToStr is " +valToStr);
