String Concatenation

The concatenation
operator + joins together two strings to form a third, new
string. Operands of other types
must be converted to strings before they can be concatenated. Examples: "35"
+ " pages long." str(35) +
" pages long." If x and y are any objects, the code str(x) + str(y) concatenates their
string representations. |
The concatenation
operator + joins together two strings to form a third, new
string. If one of the operands
is a string, the other operand can be of any type. Examples: "35"
+ " pages long." 35 + "
pages long." Any non-numeric object
can also be used in a string concatenation, because all Java objects
recognize the toString() method.
This method returns the name of the objectÕs class by default, but can
be overridden to return a more descriptive string. Thus, if x and y are any objects, the code x.toString() +
y.toString() or x + y concatenates their
string representations. |
