When the value of a private field is always assigned to in a class' methods before being read, then it is not being used to store class
information. Therefore, it should become a local variable in the relevant methods to prevent any misunderstanding.
Noncompliant code example
public class Foo
{
private int singularField;
public void DoSomething(int x)
{
singularField = x + 5;
if (singularField == 0) { /* ... */ }
}
}
Compliant solution
public class Foo
{
public void DoSomething(int x)
{
int localVariable = x + 5;
if (localVariable == 0) { /* ... */ }
}
}
