How to get the current working directory in Java?

Question

I want to access my current working directory using java.

My code :

 String current = new java.io.File( \".\" ).getCanonicalPath();
        System.ou

This is my silver bullet when ever the moment of confusion bubbles in.(Call it as first thing in main). Maybe for example JVM is slipped to be different version by IDE. This static function searches current process PID and opens VisualVM on that pid. Confusion stops right there because you want it all and you get it...

  public static void callJVisualVM() {
    System.out.println("USER:DIR!:" + System.getProperty("user.dir"));
    //next search current jdk/jre
    String jre_root = null;
    String start = "vir";
    try {
        java.lang.management.RuntimeMXBean runtime =
                java.lang.management.ManagementFactory.getRuntimeMXBean();
        String jvmName = runtime.getName();
        System.out.println("JVM Name = " + jvmName);
        long pid = Long.valueOf(jvmName.split("@")[0]);
        System.out.println("JVM PID  = " + pid);
        Runtime thisRun = Runtime.getRuntime();
        jre_root = System.getProperty("java.home");
        System.out.println("jre_root:" + jre_root);
        start = jre_root.concat("\\..\\bin\\jvisualvm.exe " + "--openpid " + pid);
        thisRun.exec(start);
    } catch (Exception e) {
        System.getProperties().list(System.out);
        e.printStackTrace();
    }
}
