How to increase the java heap size in netbeans?
java, netbeans-7
Solution
You can set it in NetBeans in the project properties -> Run -> VM options
- 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.
Problem
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 ``` I was wondering if someone could help me with increasing the java heap space in netbeans.
