Raw Normal View History

It is both suspicious and unusual to make direct assignments to super-class fields from a class constructor. Choosing to make such direct assignments, rather than invoking the ``++super++`` constructor that sets them, potentially bypasses important initialization.
== Noncompliant Code Example
----
public class Parent {
protected int start;
public Parent() {
//...
}
public Parent(int start) {
this.start = start;
}
}
public class Child extends Parent {
public Child(int start) {
this.start = start; // Noncompliant
}
}

== Compliant Solution
----
public class Parent {
protected int start;
public Parent() {
//...
}
public Parent(int start) {
this.start = start;
}
}
public class Child extends Parent {
public Child(int start) {
super(start);
}
