Strings and Object References in Java

26. Cascaded String Operations


Answer:

It creates a new String which is a lowercase version of the original string.

Cascaded 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.
