如何在netbeans中增加java堆大小？ [英] How to increase the java heap size in netbeans?

问题描述

我正在尝试在netbeans中用java构建一个近110000个单词的词典。我的代码运行正常，但它给出了一个异常，如下所示：

I am trying to build a lexicon trie of almost 110000 words in java in netbeans. My code is running fine but it gives an Exception as follows:

   Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOfRange(Arrays.java:3209)
at java.lang.String.<init>(String.java:215)
at java.nio.HeapCharBuffer.toString(HeapCharBuffer.java:542)
at java.nio.CharBuffer.toString(CharBuffer.java:1157)
at java.util.regex.Matcher.toMatchResult(Matcher.java:232)
at java.util.Scanner.match(Scanner.java:1270)
at java.util.Scanner.nextLine(Scanner.java:1517)
at lexiconbuild.model.Lexicon.<init>(Lexicon.java:29)
at lexiconbuild.model.LexiconBuild.main(LexiconBuild.java:17)
Java Result: 1

我想知道是否有人可以帮助我增加netbeans中的java堆空间。

推荐答案

您可以在项目属性中的NetBeans中设置它 - >运行 - > VM选项

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

1. 右键点击您的项目属性


2. 选择运行 类别。


3. 在 VM选项文本框中输入您的参数（ -Xmx512m ）。

1. Right click on your project "Properties"
2. Select "Run" category.
3. Enter your arguments(-Xmx512m) in the "VM Options" text box.

示例：在VM Options文本框中放置-Xmx512m可为Java程序提供512Mb的最大堆大小。

Example: Putting -Xmx512m in the "VM Options" text box gives 512Mb maximum heap size to your Java program.
