Applet

Hi All,
I need help again ...
This is from the IBM mock test
An applet is more restrictive than an application in the following ways -
a. An applet may not perform local disk IO.
b. An aplet may not connect with any server except the server where the applet was loaded from
c. An applet can change the CODEBASE
d. An applet cannot call the update() method directly
I think b is true...
44. Which of the following are true with respect to Thread class.
a. Individual instances may communicate with each other.
b. Instances may always assume pre- emptive scheduling model.
c. It cannot be subclassed.
d. Each instance belongs to a ThreadGroup.
e. Unsecure / Unsigned applet may not create new instances.
here I know that a & d are true.
But I am not sure about what
e. Unsecure / Unsigned applet may not create new instances
means ?
Can anyone help me ?
Thx in advance.

Hi Aru,
For first ques.

both a and b are true.
a) -: true
An applet can't perform local input/output. means an applet can't open/read/write to the files in local m/c.
b) -: true

regarding ur second ques.

yes options a and d are right.
In case of option e) any applet be it signed/unsigned It can
create as many thread instances as it requires.
