What is the result?
passleader-1z0-808-dumps-702

A.    Option A
B.    Option B
C.    Option C
D.    Option D

Answer: D
Explanation:
If neither operand of + is a reference to a String object, the operator is the arithmetic addition operator, not the string concatenation operator. Note that Java does not allow a program to define overloaded operators. However, the language defines the + operator to have a meaning that is fundamentally different from arithmetic addition if at least one of its operands is a String object.
The way in which Java decides if + means arithmetic addition or string concatenation means that the use of parentheses can alter the meaning of the + operator.
See “String Concatenation Operator +” at
