推荐答案

你可以看看Runtime类:

You can have a look into Runtime class:

Runtime.getRuntime().maxMemory();

但来自运行时文档:

返回 Java 虚拟机的最大内存量将尝试使用.如果没有固有限制，则该值Long.MAX_VALUE 将被返回

Returns the maximum amount of memory that the Java virtual machine will attempt to use. If there is no inherent limit then the value Long.MAX_VALUE will be returned
