Getting the bookClasses to work with DrJava



Overloading of Methods
   - when two or more methods exist with the
     same name.
   - the method that gets executed is the one that
     has its parameter list match the number
     and type of parameters in the method call.


Loops - allows a section of code to do the same
     thing (or almost the same thing) over and over.

  Java has a number of looping statement

     while loop, for loop, do-while loop

  General form of a while loop

     <initializationStatement> ;
     while  ( <conditionStatement> )
         {
           <bodyStatements> ;

           <incrementStatement> ;
         }

  Example:  a Loop that prints the values from 1 to 6

       int loopCounter;
       loopCounter = 1;

       while ( loopCounter <= 6 )
         {
           System.out.println (loopCounter);
           loopCounter = loopCounter + 1;
         }

  Relational Operators

      <   less than
      >   greater than
      <=  less than or equal
      >=  greater than or equal
      ==  equality 
      !=  inequality 

  A while loops executes the statements in the body
    while the condition is true.
