E) Many times the compiler is able to detect the attempted use of an uninitialized variableit will generate a syntax error in this case. If such as use escapes detection by the compiler then a runtime error occurs upon usage. Java is a very "safe" language, so it does not allow "garbage" or zero to be used if an uninitialized variable is used in a computation.
