Lambda can be replaced with anonymous class

Reports lambda expressions that can be replaced with anonymous classes.

Expanding lambda expressions to anonymous classes may be useful if you need to implement other methods inside an anonymous class.

Example:

s -> System.out.println(s)

After the quick-fix is applied:

new Consumer<String>() {
  @Override
  public void accept(String s) {
    System.out.println(s);
  }
}

Lambda expression appeared in Java 8. This inspection can help to downgrade for backward compatibility with earlier Java versions.
