building file and variable names from variables

Hi,

I'm fairly new to java, but need some help with converting what is an easy action in scripting languages but usually not so easy in programming languages. In scripting I would do the following (in pseudo-codish):

for i=0 , i<10 , i++
print "hello world no. $i"
open "filename$i"
readin "filename$i"
var.$i = var.$i + var.$(i-1)
done

Note the use of the $i. How can I do this in Java? I can do it in C and Fortran, but can't seem to find a reference on how to do it in Java. (The specific commands I used above are an example only)

Thanks for your help.

As far as i see, you are interested in concatenating a string with an integer. Lets assume that you have a string variable str and an int variable i. You will need to create an Integer object from your int primitive value and concatanete as follows:

Code:

---

String combined = str + (new Integer(i).toString());

---

Thanks. That's what I was looking for! :-)
