Java - Design Pattern - Inversion of Control

<source lang="Java"> //Your standard code would look something like this: public class TextEditor {

   private SpellChecker checker;

   public TextEditor() {
       this.checker = new SpellChecker();
   }

}

//In an IoC scenario we would instead do something like this: public class TextEditor {

   private IocSpellChecker checker;

   public TextEditor(IocSpellChecker checker) {
       this.checker = checker;
   }

}

//This allows us to call the dependency then pass it to the TextEditor class like so: SpellChecker sc = new SpellChecker; // dependency TextEditor textEditor = new TextEditor(sc);

//With spring public class TextEditor {

   @Autowire
   private IocSpellChecker checker;

   //rest of the class
