Assigning a value to a static field in a constructor could cause unreliable behavior at runtime since it will change the value for all
instances of the class.
Instead remove the field’s static modifier, or initialize it statically.
Noncompliant code example
public class Person
{
private static DateTime dateOfBirth;
private static int expectedFingers;
public Person(DateTime birthday)
{
dateOfBirth = birthday; // Noncompliant; now everyone has this birthday
expectedFingers = 10; // Noncompliant
}
}
Compliant solution
public class Person
{
private DateTime dateOfBirth;
private static int expectedFingers = 10;
public Person(DateTime birthday)
{
this.dateOfBirth = birthday;
}
}
