And some common method (To implement each method, just print out the function name, like the function of eat() is printing eat on your screen. All methods should use this rule no matter it is common or particular to an animal):

1. eat()
2. talk()
3. sleep()

Beside these common variables and methods, please notice that Dog has a method called bark(), Cat has a method called meow(), and Bird has a method called chirp().

What you need to do is:

Define all animals. Then in your main() method, print out all functions each animal can do.

Hint: dont forget to use superclass to save your time.

Write the Java program to implement the following flowchart: Declare the char variable named grade Assign a letter to grade Check the value of grade Print "90-100" Print "80-89" Print 70-79" | Print 60-69" Print"
