Heap Sort Algorithm Studytonight
Mar 31 2016 nbsp 0183 32 However it appears that when I try and add elements past a certain point the values are different when I try to access them I understand that this is because there is only a finite amount of memory on the stack as opposed to the heap which has more memory I have tried the following without much luck does not compile How Do I Create An Array In C Which Is On The Heap Instead Of . The free heap space reported by these MBeans will vary greatly depending on GC behaviour particularly if your application generates a lot of objects which are later GC ed One possible approach is to monitor the free heap space after each full GC which you may be able to use to make a decision on freeing up memory by persisting objects In terms of Java heap size in Linux you can use ps aux grep java or ps ef grep java and look for Xms Xmx to find out the initial and maximum heap size specified However if Xms or Xmx is absent for the Java process you are interested in it means your Java process is using the default heap sizes
