Example 56 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class Java2GroovyProcessor method processFiles.

public static void processFiles(List<String> fileNames) throws Exception {
    Iterator i = fileNames.iterator();
    while (i.hasNext()) {
        String filename = (String) i.next();
        File f = new File(filename);

    }
}
