#1395 UnusedPrivateMethod false positive for array element method call

[Patrick McEvoy]

A method is incorrectly flagged as unused when only called with an array element method return. The workaround is to get the element then call the method.

Example

    public void doSomething() {
        File[] files = getFiles();
        for (int i = 0; i < files.length; i++) {
            String name = getNameFromFilename(files[i].getName());
            System.out.println("name is " + name);
        }
    }

    private String getNameFromFilename(String fileName) {
        int index = fileName.lastIndexOf('.');
        return fileName.substring(0, index);
    }

This will be fixed with PMD 5.3.4.
