this.x = x; Effectively you wrote this.x = this.x; because there is no x parameter. // This method does nothing, // just sets this.brush to itself. // Note misspelling brash for Alternatively, you can throw out all the imports and fully qualify all classes in x.y and a.b. For example, TestGenericMethod.ArrayToArrayList(intArray, lst); The syntax makes the code more readable and also gives you control over the generic type in situations where the type might not be obvious. fixed. –dseibert Mar 24 '11 at 3:11 | show 1 more comment Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using
