Java code displaying error on for loop

Question

What's the problem in this Java code,there is a constant red line under the for loop, the code does work in a Java class but not in this one:

<%!
          EntityManagerFactory emf = javax.persistence.Persistence.createEntityManagerFactory("Dima_TestPU");
        RegionJpaController djc = new RegionJpaController(emf); 
        List<Region> lstRegion = djc.findRegionEntities(); 
        for( Region device : lstRegion ) {
            System.out.println(device.getId());
            System.out.println(device.getName());
            System.out.println(device.getLatitude());
        }
%>

It's because JavaScript has nothing to do with Java. You are messing around with syntax of different languages.

In JavaScript for loop looks like this:

for (var i in myArray) {
    console.log(myArray[i]);
}

or

for (var i = 0; i < myArray.length; i++) {
    console.log(myArray[i]);
}
