Java generics ❓ 

//----------------------- Generic Method ----------------------- public class Main { public static void main(String args[]) { Integer[] intArray = {1, 2, 3, 4, 5}; Double[] doubleArray = {5.5, 4.4, 3.3, 2.2, 1.1}; Character[] charArray = {'H', 'E', 'L', 'L', 'O'}; String[] stringArray = {"B","Y","E"}; System.out.print("Integer Array: "); displayArray(intArray); System.out.println(firstIndex(intArray)); System.out.print("Double Array: "); displayArray(doubleArray); System.out.println(firstIndex(doubleArray)); System.out.print("Character Array: "); displayArray(charArray); System.out.println(firstIndex(charArray)); System.out.print("String Array: "); displayArray(stringArray); System.out.println(firstIndex(charArray)); */ } // Generic method public static void displayArray(Thing[] array) { for(Thing x : array) { System.out.print(x+" "); } System.out.println(); } // Generic method with generic return type public static Thing firstIndex(Thing[] array) { return array[0]; } } //----------------------- Generic Class ----------------------- public class Main { public static void main(String args[]) { //bounded types = you can create the objects of a generic class to have data // of specific derived types ex.Number MyGenericClass myInt = new MyGenericClass(1,9); MyGenericClass myDouble = new MyGenericClass(3.14,1.01); //MyGenericClass myChar = new MyGenericClass('@','$'); //MyGenericClass myString = new MyGenericClass("Hello",'!'); System.out.println(myInt.getValue()); System.out.println(myDouble.getValue()); //System.out.println(myChar.getValue()); //System.out.println(myString.getValue()); } } // ---------------------------------------------------------------- public class MyGenericClass { Thing x; Thing2 y; MyGenericClass(Thing x, Thing2 y){ this.x = x; this.y = y; } public Thing2 getValue() { return y; } }

Single-handedly taught me Generics and helped me complete an assignment in 30 minutes. Epic!
