There are two methods: use java.lang.Runtime.exec(...How to launch One Java Program from another Java Program
I am new to Java and here is my question:
How to launch another Java program from within a Java program?
I have tried using Runtime.getRuntime() and it works for launching
But if I need to launch another java program do I have to use:
"Java <another Java program name>" => This string as an input to exec()
method to run another Java program?
Both the programs will run on the same machine. Can these program share
the same JVM and run in the same process?
I want to avoid using RMI.

Im in need of some help..frustrated with this one!
Im looking to write a program to find the mean of the means of a
variable. For example, I have multiple doses for each patient and
want to calculate the patient dose means as well as the total dose mean
using these patient means. A simple proc means calculates the patient
means just fine. Can anyone suggest how to output these means to in
turn run another proc means????
Any suggestions appreciated! thanks!
you might simply use 2 proc means or summary with output datasets:
proc summary nway data=in;
v...100^100 != 100^100
a = 100^100; str2num(num2str(a)) == a
results in 1
Howcome? What is the best way to deal with such large numbers in
MATLAB? How can I see the number without num2str function?

...java.lang.Set with elements of type java.lang.Set
Roughly I do something along the lines of:
Set set = new HashSet();
Set elem = new HashSet();
// now we change the elem and add it again to the set
elem.add(some object here);
I found out the hard way that 'set' may now contain
'elem' either once or twice, the reason being that
'elem.add()' changes the hashCode of elem such that
it is not noticed that it is in 'set' already on the

i knew that by default all java.lang classes will be imported by the
compiler during compilation. but, to make it easier for the computer,
should i specify which class i really will be using? does this action
will boost the performance during compilation and runtime or not a
matter at all?
the answer to this post will definitely affect my programming style in
the future when i'm considering "to import or not to import"...
thanks in advance.
