| 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 object’s class by default, but can be overridden to return a more descriptive string. Thus, if x and yare any objects, the code x.toString() + y.toString() or x + y concatenates their string representations. |
