Question

I’m getting this compiler error in netbeans:

incompatible types
required: String
found: java.lang.String

I’m kind of lost as why this happens?

Code:

private class StringIterator<String> implements Iterator<String> {

    private Iterator<Entry<K, byte[]>> i = internalMap.entrySet().iterator();

    @Override
    public boolean hasNext() {
        return i.hasNext();
    }

    @Override
    public String next() {
        return decompress(i.next().getValue());// error on this line
    }

    @Override
    public void remove() {
        i.remove();
    }
}

You should remove the type argument from the StringIterator class. This is causing the compiler to consider any occurrence of String in the class to be a generic type rather than java.lang.String.

private class StringIterator implements Iterator<String> {
