== Why is this an issue?

include::../description.adoc[]

=== Noncompliant code example

[source,java]
----
public void example() {
  for (Foo obj : (List<Foo>) getFoos()) {  // Noncompliant; cast unnecessary because List<Foo> is what's returned
    //...
  }
}

public List<Foo> getFoos() {
  return this.foos;
}
----

=== Compliant solution

[source,java]
----
public void example() {
  for (Foo obj : getFoos()) {
    //...
  }
}

public List<Foo> getFoos() {
  return this.foos;
}
----

=== Exceptions

Casting may be required to distinguish the method to call in the case of overloading:

[source,java]
----
class A {}
class B extends A{}
class C {
  void fun(A a){}
  void fun(B b){}

  void foo() {
    B b = new B();
    fun(b);
    fun((A) b); //call the first method so cast is not redundant.
  }

}
