How do I check CPU and Memory Usage in Java?

If you are looking specifically for memory in JVM: Runtime runtime = Runtime.getRuntime(); NumberFormat format = NumberFormat.getInstance(); StringBuilder sb = new StringBuilder(); long maxMemory = runtime.maxMemory(); long allocatedMemory = runtime.totalMemory(); long freeMemory = runtime.freeMemory(); sb.append(“free memory: ” + format.format(freeMemory / 1024) + “<br/>”); sb.append(“allocated memory: ” + format.format(allocatedMemory / 1024) + “<br/>”); sb.append(“max memory: ” … Read more

How can I measure CPU time and wall clock time on both Linux/Windows?
