String / Variable Concatenation

Hi all, I'm trying to build a variable name automatically through a for loop for a script I'm working on, basically I want to build the variables named: $JVM_HOME0 or $JVM_HOME1 so that I can loop through some file copy/deletes and a server restart once completed. With the code below, I get this for the ouput:
JVM Home 0 is: 0
JVM Home 1 is: 1
which is the value of $i, I need to get back either "test" or "TEST2". Is there a way to do this? If it helps, I'm doing this on bash version 3.2.25(1)-release....


Code:
 
#!/bin/bash

JVM_COUNT=2
JVM_HOME0="test"
JVM_HOME1="TEST2"

for (( i=0; i<$JVM_COUNT; i++ ))
 do
    echo JVM Home $i is: $JVM_HOME$i
 done

Thanks !
