What does the class name .class in java mean?

The class name in Java.class represents the bytecode file object of the class.

Detailed explanation:

When a Java program is compiled, each class will be compiled into a bytecode file (.class file). Bytecode is an intermediate code that can be understood by the Java Virtual Machine (JVM). It contains the structure, methods and field information of the class.

Class name.class represents the Class object that refers to the bytecode file object. The Class object provides information about the class and its members, for example:

  • Class name
  • Method list
  • Field list
  • Constructor list

Uses:

Class name.class has many uses in Java, including:

  • Get information about a class
  • Create an instance of a new class
  • Access the methods and fields of the class
  • Compare two classes for equality
  • Load a pre-compiled class

Example:

The following example uses classname.class to get information about the String class:

Class<?> stringClass = String.class;
System.out.println("String类的名称:" + stringClass.getName());
System.out.println("String类的父类:" + stringClass.getSuperclass().getName());
