== Noncompliant Code Example

----
public class Parent {

  public Parent () {
    doSomething();  // Noncompliant
  }

  public void doSomething () {  // not final; can be overridden
    ...
  }
}

public class Child extends Parent {

  private String foo;

  public Child(String foo) {
    super(); // leads to call doSomething() in Parent constructor which triggers a NullPointerException as foo has not yet been initialized
    this.foo = foo;
  }

  public void doSomething () {
    System.out.println(this.foo.length());
  }

}
