Autoboxing on the other hand, can also produce more subtle effects. It works by automatically wrapping the primitive type to the corresponding wrapper object. Some care should be taken during this process, especially when performing comparisons. The Java Language Specification \[[JLS 05|AA. Java References#JLS 05]\] explains this point clearly: |
