Method Overloading Tasks

Method Overloading Tricky Questions : class Test { void show ( int a ) { } void show ( long a ) { } public static void main ( String [] args ) { Test t = new Test (); t . show ( 10 ); } } ANSWER: show(int a) 10 is int → exact match is preferred over widening (int → long) class Test { void show ( Integer a ) { } void show ( int a ) { } public static void main ( String [] args ) { Test t = new Test (); t . show ( 10 ); } } ANSWER: show(int a) Exact primitive match is preferred over autoboxing (int → Integer) class Test { void show ( int a , float b ) { } void show ( float a , int b ) { } public static void main ( String [] args ) { Test t = new Test (); t . show ( 10 , 10 ); } } ANSWER: Compile-time error (Ambiguous) Both require one widening conversion → compiler confused class Test { void show ( int ... a ) { } void show ( int a ) { } public static void main ( String [] args ) { Test t = new Test (); t . show ( 10 ); } } ANSWER: show(int a) Normal method > varargs class Test { void sho
