String last; // Person’s last name

String middle; // Person’s middle initial

publicName() throwsIOException // Gets a name from System.in

{

BufferedReader in; // Input stream for strings

// Instantiate in using System.in

in = newBufferedReader(newInputStreamReader(System.in));

System.out.print(“Enter first name: “); // Prompt for first name

first = in.readLine(); // Get first name

System.out.print(“Enter last name: “); // Prompt for last name

last = in.readLine(); // Get last name

System.out.print(“Enter middle initial: “); // Prompt for middle initial

middle = in.readLine(); // Get middle initial

}

publicString firstLastFormat () // Returns name in first-last format

{

returnfirst + “ “+ last;

}

publicString lastFirstMiddleFormat() // Returns name as last, first, m.

{

returnlast + “, “+ first + “, “+ middle + “.”;

}

} // End of Name Class

// Driver for testing Name class
public static voidmain(String[] args) throwsIOException
{
Name testName; // Declare a name
testName = newName(); // Instantiate a name
System.out.println(“Name in first-last format is “+
testName.firstLastFormat()); // First format
System.out.println(“Name in last-first-initial format is “+
testName.lastFirstMiddleFormat()); // Second format
}
}

The output from the program follows:
