我尝试java --version在命令行中得到:

Unrecognized option: --version
Error: Could not create the Java virtual machine
Error: A fatal exception has occurred. Program will exit.

一切都工作正常,直到我安装了jre 7(我预装了jdk 1.6)所以,我卸载了以前的版本,重新启动然后安装了新的jdk 7u5 windows i586.

            System.out.println("You have " +(500+i)+ " shares of IBM");
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            System.out.println(Thread.currentThread().getName()+e.toString());
        }}
    }


}

这是我称之为线程的地方

public class TestThreads {

    /**
     * @param args
     */

    public static void main(String[] …
