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 since Java does not provide any indication of these conditions and silently wraps (Java throws only a division by zero exception).
The following excerpt is from the Java Language Specification (Overflow)
"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"
