Getting the component type of an array

For arrays only, JDK 12 provides the Class<?> componentType() method. This method returns the component type of the array, as shown in the following two examples:

Pair[] pairs = new Pair[10];String[] strings = new String[] {"1", "2", "3"};// class modern.challenge.PairSystem.out.println("Component type of Pair[]: "   + pairs.getClass().componentType());// class java.lang.StringSystem.out.println("Component type of String[]: "   + strings.getClass().componentType());
