C++11's new auto keyword is different |
|||
Line 19:
(Called ''local variables''.)
Similar to C and C++, but there is no <code>auto</code> or [[register keyword|<code>register</code> keyword]]. However, the Java compiler will not allow the usage of a not-explicitly-initialized local variable and will give a compilation error (unlike C and C++ where the compiler will usually only give a warning). The Java standard demands that every local variable must be explicitly initialized before being used.<ref>{{cite web | url=http://java.sun.com/docs/books/jls/third_edition/html/typesValues.html#4.12.5 | title=4.12.5 Initial Values of Variables | publisher=Sun Microsystems | accessdate=2008-10-17}}</ref> This differs from instance variables, which are implicitly initialized with default values (which are <tt>0</tt> for numbers and <tt>null</tt> for objects).
