JAVA Object Oriented Programming Interfaces and Abstract Classes
Solution for Object-Oriented Programming for backend developers
/
/Coding Steps — Object-Oriented Programming:
// 1• Create an interface named Logger.
// 2• Add two void methods to the Logger interface, each should take a String as an argument
// 3• Log
// 4• Error
// 5• Create two classes that implement the Logger interface
// 6• AsteriskLogger
// 7• SpacedLogger
// 8• The log method on the AsteriskLogger should print out the String it receives between 3 asterisks on either side of the String (e.g. if the String passed in is “Hello”, then it should print **Hello** to the console).
// 9• The error method on the AsteriskLogger should print the String it receives inside a box of asterisks, with the String preceded by the word “ERROR:”. For example, if “Hello” is the argument, the following should be printed:
//
//****************
//***Error: Hello***
//****************
// 10• The SpacedLogger should add spaces between each character of the String argument passed into its methods.
// 11• If the log method received “Hello” as an argument, it should print H e l l o
// 12• The error method should do the same, but with “ERROR:” preceding the spaced-out input (i.e. ERROR: H e l l o)
// 13• Create a class named App that has a main method.
// 14• In this class instantiate an instance of each of your logger classes that implement the Logger interface.
// 15• Test both methods on both instances, passing in Strings of your choice.
