"The (Java) language is type-safe, and the runtime provides automatic memory management and range-checking on arrays. These features also make Java programs immune to the stack-smashing and buffer overflow attacks possible in the C and C++ programming languages, and that have been described as the single most pernicious problem in computer security today."
While this statement is in fact true, the arithmetic operations in the Java platform require the same caution as in C\C++. Integer operations can result in overflow or underflow because Java does not provide any indication of these conditions and silently wraps (Java throws only a division by zero exception).

"The built-in integer operators do not indicate overflow or underflow in any way. Integer operators can throw a NullPointerException if unboxing conversion of a null reference is required. Other than that, the only integer operators that can throw an exception are the integer divide operator /_ and the integer remainder operator_ %, which throw an ArithmeticException if the right-hand operand is zero, and the increment and decrement operators ++ and - which can throw an OutOfMemoryError if boxing conversion _is required and there is not sufficient memory available to perform the conversion."
See the following example.
