Why is this an issue?
Creating temporary primitive wrapper objects only for String conversion or the use of the compareTo method is
inefficient.
Instead, the static toString or compare method of the primitive wrapper class should be used.
Noncompliant code example
new Integer(myInteger).toString(); // Noncompliant
Integer.valueOf(myInt).compareTo(0); // Noncompliant
Compliant solution
Integer.toString(myInteger); // Compliant
Integer.compare(myInteger, 0); // Compliant
