It creates a new String
which is a lower case version of
the original string.
String
Operations
Sometimes a method of a String
creates another String
,
and then a method of that second String
is invoked to create a third String
(and so on).
This is sometimes called a cascade.
Usually a cascade involves intermediate temporary objects.
Look at these lines of code:
String burns = "My love is like a red, red rose."; . . . . . . if ( burns.toLowerCase().startsWith( " MY LOVE".trim().toLowerCase() ) ) System.out.println( "Both start with the same letters." ); else System.out.println( "Prefix fails." );
What is printed?
Decide what string owns the startsWith
method, and then decide what parameter it is called with.
What does the above write to the monitor?
