今天上班跑项目的时候,多次出现Java.lang.OutOfMemoryError这个异常,并且让我关闭重新启动eclipse程序。 从这个异常可以看出,JVM需要使用的内存已经超出了我们分配给虚拟机的可以使用的最大的内存了,所以,就需要在eclipse中设置jvm的最大内存。我使用的步骤如下: (1) (2) 这样便完成了。
Exception in thread "Image Fetcher 0" java.lang.OutOfMemoryError: Java heap space 解决方法: 在Eclipse里选:Window->Preference->Installed JREs->Edit(选中jre), 在Default VM Arguments里输入-Xms256m -Xmx1024m,表示最小内存256M,最大1G,然后运行就可以了。 程序源码ImageBrowser.java : importjava.awt...
