== Why is this an issue?

Rather than creating a boxed primitive from a `String` to extract the primitive value, use the relevant `parse` method instead.
Using `parse` makes the code more efficient and the intent of the developer clearer.


=== Noncompliant code example

[source,java,diff-id=1,diff-type=noncompliant]
----
String myNum = "42.0";
float myFloat = new Float(myNum);  // Noncompliant
float myFloatValue = (new Float(myNum)).floatValue();  // Noncompliant
int myInteger = Integer.valueOf(myNum); // Noncompliant
int myIntegerValue = Integer.valueOf(myNum).intValue(); // Noncompliant
----


=== Compliant solution

[source,java,diff-id=1,diff-type=compliant]
----
String myNum = "42.0";
float f = Float.parseFloat(myNum);
int myInteger = Integer.parseInt(myNum);
----

@Ann, for me this RSPEC fully duplicates RSPEC-2131, what's the difference ? Thanks

\[~freddy.mallet] they go in opposite directions. This one is string-to-primitive. The other is primitive-to-string. S'okay?
