import java.lang.reflect.Modifier;

public class ClassModifier {

        getClassModifier(String.class);
        getClassModifier(TestA.class);
        getClassModifier(TestB.class);
    }

    private static void getClassModifier(Class<?> clazz) {
        int modifier = clazz.getModifiers();

        // Return true if the integer argument includes the public modifier,
        // false otherwise.

        if (Modifier.isPrivate(modifier)) {

        }

        // Return true if the integer argument includes the static modifier,

        if (Modifier.isStatic(modifier)) {
            System.out.println(clazz.getName() + " class modifier is static");
        }

        // Return true if the integer argument includes the final modifier,
        // false otherwise.
        if (Modifier.isFinal(modifier)) {
            System.out.println(clazz.getName() + " class modifier is final");
        }

        // Return true if the integer argument includes the abstract modifier,
        // false otherwise.
        if (Modifier.isAbstract(modifier)) {
            System.out.println(clazz.getName() + " class modifier is abstract");
        }
    }

    protected static final class TestA {
    }

    private abstract class TestB {
    }
}

The code snippet prints the following output:

java.lang.String class modifier is public
java.lang.String class modifier is final
org.kodejava.lang.reflect.ClassModifier$TestA class modifier is protected
org.kodejava.lang.reflect.ClassModifier$TestA class modifier is static
org.kodejava.lang.reflect.ClassModifier$TestA class modifier is final
org.kodejava.lang.reflect.ClassModifier$TestB class modifier is private
org.kodejava.lang.reflect.ClassModifier$TestB class modifier is abstract
