Class Literal

A class literal gives a program a Class object without creating an instance.

ClassLiteral.java

public class ClassLiteral {
    public static void main(String[] args) {
        int choice = ;
        Class<?> type;

        if (choice == 1) {
            type = String.class;
        } else if (choice == 2) {
            type = Integer.class;
        } else {
            type = Boolean.class;
        }

        System.out.println("simple=" + type.getSimpleName());
        System.out.println("package=" + type.getPackageName());
    }
}

public class ClassLiteral {
    public static void main(String[] args) {
        int choice = ;
        Class<?> type;

        if (choice == 1) {
            type = String.class;
        } else if (choice == 2) {
            type = Integer.class;
        } else {
            type = Boolean.class;
        }

        System.out.println("simple=" + type.getSimpleName());
        System.out.println("package=" + type.getPackageName());
    }
}

public class ClassLiteral {
    public static void main(String[] args) {
        int choice = ;
        Class<?> type;

        if (choice == 1) {
            type = String.class;
        } else if (choice == 2) {
            type = Integer.class;
        } else {
            type = Boolean.class;
        }

        System.out.println("simple=" + type.getSimpleName());
        System.out.println("package=" + type.getPackageName());
    }
}

class literal The `.class` syntax asks Java for metadata about a type.

Class object A Class object describes a type and exposes names, package data, methods, fields, and constructors.
