java - Finding out what the NewSize is from code -

-

is possible display java newsize parameter same way can find heap size?

i know heap size can found using:

runtime.getruntime().maxmemory();

is there similar newsize?

you want memorypoolmxbean numerical values of eden space , survivor space:

for(java.lang.management.memorypoolmxbean memorypoolmxbean :java.lang.management.managementfactory.getmemorypoolmxbeans()) {     system.out.println("");     try     {         system.out.println("poolname\t" + memorypoolmxbean.getname());         system.out.println("commited\t" + memorypoolmxbean.getcollectionusage().getcommitted());         system.out.println("init\t" + memorypoolmxbean.getcollectionusage().getinit());         system.out.println("max\t" + memorypoolmxbean.getcollectionusage().getmax());         system.out.println("used\t" + memorypoolmxbean.getcollectionusage().getused());     }     catch (nullpointerexception npex)     {         npex.printstacktrace();     } }

output:

poolname    code cache java.lang.nullpointerexception     @ com.github.lyubent.example.app.main(app.java:40)  poolname    par eden space commited    0 init    335544320 max 335544320 used    0  poolname    par survivor space commited    0 init    41943040 max 41943040 used    0  poolname    cms old gen commited    0 init    1728053248 max 1728053248 used    0  poolname    cms perm gen commited    0 init    21757952 max 85983232 used    0
