Edit Question
Title
Body
I have added three methods with parameters: public static void doSomething(Object obj) { System.out.println("Object called"); } public static void doSomething(char[] obj) { System.out.println("Array called"); } public static void doSomething(Integer obj) { System.out.println("Integer called"); } When I am calling doSomething(null) , then compiler throws error as ambiguous methods . So is the issue because Integer and char[] methods or Integer and Object methods?
