class MyClass { // This class is not abstract } abstract class MyAbstractClass { // This class is declared as abstract } public class Example { public static void main(String[] args) { System.out.println(Modifier.isAbstract(MyClass.class.getModifiers())); // false System.out.println(Modifier.isAbstract(MyAbstractClass.class.getModifiers())); // true } }The example code above creates two classes, one of which is declared as abstract, and then uses the isAbstract() method to determine if each of them is an abstract class. The output of the program is `false` for the first class and `true` for the second class. The java.lang.reflect.Modifier class is part of the Java Standard Library and is located in the java.lang.reflect package.
