Easy way to Construct Strings
String
objects are very useful and are frequently used. To make life easier for programmers Java has a short-cut way of creating aString
object:
String zeta = "The last rose of summer" ;
This creates a
String
object containing the characters between quote marks. AString
created in this short-cut way is called a String literal.Remember that if several statements in a program ask for literals containing the same characters only one object will actually be constructed (see chapter 41). Other classes do not have short-cuts like this. Objects of most classes are constructed by using the
new
operator.
