Unit 5 – Writing Classes in AP Computer Science A
Topic 5.7
Why does the following example class not compile? class ClassName { public static String variableName; public void methodName() { variableName = "exampleString"; } // Constructor not shown }
The non-static method "methodName()" tries to set the value of the instance variable "variableName."
The static method "methodName()" tries to set the value of the instance variable "variableName."
It does compile because a non-static method called "methodName()" tries to set the value of a static variable, "variableName."
The static method "methodName()" tries to set the value of the static variable "variableName."
