Develop a main method, stored in a java file called Multi.java,  for the provided objects that does the following: 

• Multidimensional array of animals:
  • Animal[][]list = new Animal[3][15];
  • Sugg: Use the row to keep track of the type of animal, such that all elements in list[0] are Animals, list[1] is Dogs and list[2] is RescueDogs
• Randomly establish animals to fill the array
• Sort each row by either animal height or weight
• Display the array in an easy to read manner
  • Sugg: Override toString in all object classes
• Calculate the total height and weight:
  • For all Animals
  • For all Dogs
  • For all RescueDogs
• Calculate the average height and weight for each of the following (separately):
  • For all Animals
  • For all Dogs
  • For all RescueDogs

Notes:

• You can develop additional methods in the object classes to establish any part of the above requirements.
  • Sugg: create a print method or override toString in each class
• You can use instance of within an if/else statement to determine the actual type of a reference. Example:
  • if( animal[i] instance of Animal){

//do something with the animal references

}

• if( animal[i] instanceof Dog){

//do something with the dog references

}

• if( animal[i] instanceof RescueDog){

//do something with the rescue dog references

}
