How this method has NPath complexity of 1152? How can i reduce it?

Question

How can this method have NPATH complexity of 1152? I don't see any branches in this code unless it is adding complexity of StringBuilder.append.

Answer 1

You could create a method like

private void addToSB (String data, StringBuilder mab) {

    if (data == null)
        return;
    mab.append (data);
}

then call it as

addToSB (data[0], mab);
