我遇到的问题是java虚拟机根本没有足够的内存来编译。我该怎么办呢？
jvm由eclipse运行，它已经是64位服务器的一部分。我在一个类中运行大约600行代码，依赖于其他几个类，读取数据并保存在文本文件中。
错误报告如下所示
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (malloc) failed to allocate 1048576 bytes for
AllocateHeap
Possible reasons:
The system is out of physical RAM or swap space
In 32 bit mode, the process size limit was hit
Possible solutions:
Reduce memory load on the system
Increase physical memory or swap space
Check if swap backing store is full
Use 64 bit Java on a 64 bit OS
Decrease Java heap size (-Xmx/-Xms)
Decrease number of Java threads
Decrease Java thread stack sizes (-Xss)
Set larger code cache with -XX:ReservedCodeCacheSize=
