True or False: The String class’s replace method can replace individual characters, but cannot replace substrings.
Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."

1. Convert the UML class diagram above into a java code with the following conditions
The methods in the Pet class are abstract.
ownerName: String,
colourofFeathers:String)
+ getColourOfFeathers (): String
Create a class called test. The main() method in the test class should create three
Cat objects and two Budgie objects. The main() method should also create
indirectly an object of the Pet class.
Demonstrate polymorphism in your test class.
