A "for" expression that does not compile

Question

This is a for loop from a snippet of code that does not compile in my J2SE 1.4.2 environment:
for (int i: Units.parseRange(range_, 1, pagecnt)) {
Can someone tell me what it means and what the 1.4.2 equivalent is?

Answer 1

Does this mean there is no way that I can compile it in 1.4.2?
I mean, is there an option that enables it?Yes and No... That is, yes using the 5.0 ( 1.5.0 ) beta 2, you can compile to 5.0 ( 1.5.0 ) to 1.4 using the -source and -target switches using 1.4 features only...
but if you use 5.0 ( 1.5.0 ) features, it will not compile to 1.4 , it will give you an error stating that the feature is not supported by 1.4...
So your code snippet would need to be re-written to 1.4 code to work with 1.4.x JVMs ...
Here is an example of the For-Each aka Enhanced For loop written in 5.0 ( 1.5.0 ) beta2 :
public class ForEachArray {
        public static void main ( String [] args ){
                    int[] ar = {1,2,3,4,5,6,7,8,9,0};
                    for (int i:ar){ // For-Each loop
                         System.out.println(i);
}Which the equivalent in 1.4 would be :
public class ForLoopArray {
        public static void main ( String [] args ){
                    int[] ar = {1,2,3,4,5,6,7,8,9,0};
                    for (int i = 0; i < ar.length; i++ ){ // for loop
                         System.out.println(ar);
Hope this answers some of your question, now if you want help with that code snippet, naturally I will need to see some more code related to the snippet so that I can assist you in re-writing it to 1.4 version...
