Java类可以具有的最大字段数是多少? [英] What is the maximum number of fields a Java class can have?

问题描述

java类或关联的对象实例可以具有的字段数是否有限制，如果可以的话，这是什么?

Is there a limit to the number of fields a java class or an associated object instance can have, and if so what is it?

我明确询问字段，而不是询问此问题的方法: 一个方法的最大数量是Java类可以拥有吗?

I am explicitly asking about fields, not methods as was asked in this question: What is the maximum number of methods a Java class can have?

推荐答案

在JVM规范中，它说:

In the JVM spec it says:

类或接口可以声明的字段数为 由ClassFile的fields_count项的大小限制为65535 结构(第4.1节)

The number of fields that may be declared by a class or interface is limited to 65535 by the size of the fields_count item of the ClassFile structure (§4.1)
