toString method in the Class course?****************
Have a look at how println is implemented. Look in src.zip.
In essence it looks something like this
void println ( Object o )
{
// the console needs a string of chars. I just have an object
// so I will call the the toString method which every object has
// or overrides.
sendToConsole ( o.toString() );
println();
}
Why? How else would you get a String to print?
