Please what is the difference between

textA = text;
textA = new String(text);

Thank you

Welcome to JavaRanch!

The first one makes the variable point to an existing String; the second creates a new String. There is almost never (and by almost never I mean only in one or two very advanced cases that you're unlikely to ever run into) any reason to use the String(String) constructor. Always use your first version, not the second.
