String Concatenation Operator

• If either operand is a String, the + operator concatenates the operands.
• If both operands are numeric, the + operator adds the operands. Increment/Decrement Operators (Objective 7.6)
• Prefix operators (++ and --) run before the value is used in the expression.
• Postfix operators (++ and --) run after the value is used in the expression.
• In any expression, both operands are fully evaluated before the operator is applied.
• Variables marked final cannot be incremented or decremented.
