Rather than creating a boxed primitive from a String to extract the primitive value, use the relevant parse method
instead. It will be clearer and more efficient.
Noncompliant Code Example
String myNum = "12.2";
float f = (new Float(myNum)).floatValue(); // Noncompliant; creates & discards a Float
Compliant Solution
String myNum = "12.2";
float f = Float.parseFloat(myNum);
