You can set it in NetBeans ide in the project properties -> Run -> VM options

您可以在项目属性 - >运行 - > VM选项中的NetBeans ide中进行设置

Right click on your project "Properties" Select "Run" category. Enter your arguments(-Xmx512m) in the "VM Options" text box. Example: Putting -Xmx512m in the "VM Options" text box gives 512Mb maximum heap size to your Java program.

右键单击您的项目“属性”选择“运行”类别。在“VM选项”文本框中输入参数(-Xmx512m)。示例:将-Xmx512m放在“VM Options”文本框中,为Java程序提供512Mb的最大堆大小。

It could be an error related to Netbeans itself, then consider launching Netbeans with -Xmx key as it is described here: https://performance.netbeans.org/howto/jvmswitches/

它可能是与Netbeans本身相关的错误,然后考虑使用-Xmx密钥启动Netbeans,如下所述:https://performance.netbeans.org/howto/jvmswitches/

Also it could be related to your particular project, you are trying to launch in Netbeans. In this case open project properties, go to Run section and extend memory for your project via -Xmx switch in VM Options as it is shown below:

此外,它可能与您的特定项目有关,您正尝试在Netbeans中启动。在这种情况下打开项目属性,转到Run部分并通过VM Options中的-Xmx开关为项目扩展内存,如下所示:
