Processor decimal percentage problem - JAVA

Question

Okay, guys, here’s the thing, I developed a code to pick up the percentage used by my processor core application:

private String getCPULoad() {
    OperatingSystemMXBean osBean = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
    DecimalFormat df = new DecimalFormat("#.##");
    return (df.format(osBean.getProcessCpuLoad())) + "%";
}

In theory he should give me back the percentage, because well he returns it, only in the wrong way, for example: when all the cores are used at 100%, he should return me the percentage "100%", but instead he returns me 0,1%, could someone tell me what I’m doing wrong?

Answer 1

According to the documentation, the method getProcessCpuLoad returns a double between 0.0 and 1.0, so just multiply the value by 100.
