Java Runnable With Arg

RunnableWithArg.java

public interface RunnableWithArg<T> {
    
    /**
     * Similar to the runnable interface but it accepts an argument
     *
     * @param arg any type of argument
     */
    public void run(T arg);
    
}

Example of usage

Suppose to have a method like the following that needs a RunnableWithArg as callback:

CameraUtilities.takePhotoFromCamera(getTakeAvatarCallback());

in this case, the implementation of getTakeAvatarCallback() can start with:

    /**
     * Callback for taking a new avatar photo from Camera or Gallery
     * @return 
     */
    private RunnableWithArg<Image> getTakeAvatarCallback() {
       return new RunnableWithArg<Image>() {
           @Override
           public void run(Image image) {
               // write your code here
           }
       };
    }
