System.out.println("java.home: " + System.getProperty("java.home"));
   System.out.println("java.class.path: " + "java.home"+ System.getProperty("java.class.path"));
   System.out.println("java.specification.version: "+ System.getProperty("java.specification.version"));
   System.out.println("java.specification.vendor: "+ System.getProperty("java.specification.vendor"));
   System.out.println("java.specification.name: "+ System.getProperty("java.specification.name"));
   System.out.println("java.version: "+ System.getProperty("java.version"));
   System.out.println("java.vendor: "+ System.getProperty("java.vendor"));
   System.out.println("java.vendor.url: " + System.getProperty("java.vendor.url"));
   System.out.println("java.vm.specification.version: "+ System.getProperty("java.vm.specification.version"));
