static variable can be changed by both static and non-static method. The problem can not change the parameter value is due to the parameter passing is by value not by reference. Thus, in the code, you just changed the value of parameter 'a' in calling stack, not the passed variable. • 基于WEB的J2EE报表解决方案集锦 |
