long totalFree = runtime.freeMemory() + maxMemory - runtime.totalMemory();
return totalFree > maxMemory * 0.2;
StringjvmFreeMemory(String size, Boolean txtByte)
Obtain JVM's Free Memory. 
return convertByteSize(Runtime.getRuntime().freeMemory(), size, txtByte);

long mem = 0;
for (int i = 0; i < 10; i++)
    mem += runtime.freeMemory();
mem /= 10;
return mem;
