但即使在 Java 这样的高级语言中,内存管理仍然是一个重要课题。内存溢出(OutOfMemoryError)是指程序尝试使用超过其可用内存的情况,导致程序无法继续运行。了解内存溢出及其分析工具,可以帮助开发者更好地优化和调试 Java 应用程序。 内存溢出的种类 内存溢出通常分为以下几种类型: 如何检测内存溢出 检测Java 程序的内存...
java.lang.OutOfMemoryError:Javaheapspace：这种是java堆内存不够，一个原因是真不够（如递归的层数太多等），另一个原因是程序中有死循环；如果是java堆内存不够的话，可以通过调整JVM下面的配置来解决：-Xms3062m -Xmx3062m 【情况二】java.lang.OutOfMemoryError:GCoverheadlimitexceeded 【解释】...

1、缓冲区(buffer) NIO是基于缓冲区的IO方式。当一个链接建立完成后,IO的数据未必会马上到达,为了使数据到达时能够正确完成IO操作,在BIO(阻塞IO)中,等待IO的线程必须被阻塞,以全天候地执行IO操作。为了解决这种IO方式低效的问题,引入了缓冲区的概念,当数据到达时,可以预先被写入缓冲区,再由缓冲区交给线程,因此线...

got a nice 4 channel scope, i now am missing the ability to sample current data from test devices. High bandwidth current probes are obviously very expensive, but generally, for what i am doing, i don't need a very high current sampling rate (as inductance tends to limit RoC of current...
