Sample 2. Class Nested within Interface / Static Inner class within Interface

public interface SampleInterface {

   public int sampleMethod(List sampleList);



   static class Impl implements SampleInterface {



      @Override

      public int sampleMethod(List sampleList) {

         return 0;

      }

   }

}

Sample 3. Interface Default Methods ( Base Class Definition has precedence over Interface Default Method if both are being extended and implemented and have common method definition )

HelloJava8Base 



public class HelloJava8Base {

     public void defaultMethod() {

         System.out.println("Default Method Base Class Implementation");

     }

}



DefaultMethodInterface 



public interface DefaultMethodInterface {

     default public void defaultMethod() {

         System.out.println("Default Method Interface Implementation");

     }

}



HelloJava8



public class HelloJava8 extends HelloJava8Base implements DefaultMethodInterface,DefaultMethodInterface2 {

   public static void main(String[] args){

       DefaultMethodInterface dmi = new HelloJava8();

       dmi.defaultMethod(); // Prints "Default Method Base Class Implementation"

    }

}

Sample 4. Write a program to show thread usage in Java by implementing runnable interface

public class MyClass {

   static class MyThreadClass implements Runnable{



      public void start() {

         Thread t = new Thread(this,"threadName");

         t.start();

      }

      

      @Override

      public void run() {

         System.out.println("Hello");

         try {

            Thread.sleep(1000);

            System.out.println("Hello Again");

         } catch (InterruptedException e) {

            e.printStackTrace();

         }

         

      }

      

   }

   

   public static void main(String[] args){

      MyThreadClass myThreadClass = new MyThreadClass();

      myThreadClass.start();

      

      MyThreadClass myThreadClass2 = new MyThreadClass();

      myThreadClass2.start();

Sample 5. Interface Default Methods

public interface DefaultMethodInterface {

    default public void defaultMethod(){

       System.out.println("DefaultMethodInterface");        

    }

}



public interface DefaultMethodInterface2 {          

        default public void defaultMethod(){

               System.out.println("DefaultMethodInterface2");        

        }

}



public class HelloJava8 implements DefaultMethodInterface,DefaultMethodInterface2 {

   public static void main(String[] args){   

           DefaultMethodInterface defMethIn = new HelloJava8();

Sample 6. Check if an object is an instanceOf class or derived class or implementing interface

DerivedClass dc = new DerivedClass();



if (dc instanceof BaseClass) {

}

Sample 7. Get the properties of class (i.e package name , interfaces , subclasses etc ) using ClassUtils( Apache Commons )

Class class1 = ClassUtils.getClass("BuggyBreadTest"); 

System.out.println(ClassUtils.getPackageName(class1));

System.out.println(ClassUtils.getAllInterfaces(class1));

_{Like Feedback ClassUtils Apache Commons Get Class Properties java.lang.Class}

Sample 8. Usage of Java 8 Consumer interface

Consumer<String> consumer = s->{

   System.out.println(s);

};



consumer.accept("BuggyBread"); // prints BuggyBread

Sample 9. Ngrx Reducer method , State interface and Initial state variable

export interface IAppState{

   myNumber: number;

}



export const INITIAL_STATE: IAppState = {

  myNumber: 0

}



export function reducer(state,action){

  

  if(action.type == INCREMENT){

     

    let num:number[] = state.myNumber;

    let num1:number = num.length + 1;

   

    return Object.assign({},...state,{

      myNumber: state.myNumber + 1

    })

  } else {

    return state;
