java.OutOfMemoryException solution

OurJava Program is running under theJVM, jvm is heart of the java,jvm is control the whole java program. jvm is allocating the memory space for every java instance . the default memory size is 64 mb . if any java instance exceed this size then Java.OutOfMemoryException will occurs .But we can change the default jvm size in runtime .

if you want allocate 250 mb then

Syntax java -Xmx250m ClassFileName

ex : java -Xmx500m -jar soundtracker.jar
-Xmx200m HelloWorld
