Inheritance - warning when shadowing superclass variable with same name
java
Solution
Yes. In Eclipse go to
Preferences->Java->Compiler->Errors/Warnings
In that pane there is a subsection on Name shadowing and conflicts that contains the options you are looking for.
Problem
When using Java, is there a way to get a compiler warning (using Eclipse, if it matters) when a child class shadows a super class's instance variables by declaring another one of the same name? For example: ``` class A { String variable; A() { variable = "A"; } } class B extends A { int variable; B() { variable = 1; } } B b = new B(); System.out.println("Variable value: " + b.variable + ", " + ((A) b).variable); // prints out: "Variable value: 1, A" ``` I'd like to be warned in `B` that variable already exists.
