*Actually*, returning the string is *essential*, and is about the only
thing in this totally convoluted code that is on target (the other
being the assignment of temp to the result of process_me). Try it
without it (cleaning up the resulting compiler problems of course),
and you will see that it won't work.
Here is what this code should be distilled down to:
String temp = process_me();
out.println(temp);
public String process_me()
{
return "my name";
}
The following will *not* work:
String temp = null;
process_me(temp);
out.println(temp);
public String process_me(String temp)
{
temp = "my name";
return temp;
}
Nor will:
String temp = null;
process_me(temp);
out.println(temp);
public void process_me(String temp)
{
temp = "my name";
}
