This is a warming by netbean and the warming message is :
String constructor invocation surround with...
source :
String s = new String("leg");
Since String class in immutable in Java and it's not memory efficient. To correct the warming, please remove the string constructor invocation and useconstructor argument directly.
String s = "leg";
