Answer:

The class is called MyApp which inherits from JFrame and implements the ActionListener interface.

Explanation:

The class is called MyApp which extends the swing class JFrame and implements the ActionListener interface for event handling. As a results it needs to implement a method called actionPerformed for handling the relevant events that may be raised from the user interface. Since it extends JFrame, it has access to all the public and protected methods defined in JFrame(for example setTitle to set the title of the frame).

A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter

trapecia [35]

Answer:

5 Letters

Explanation:

So we need 12 distinct codes made of a single letter or a pair of letters.

What would be the least number of letters?

Lets try with 3 letters A, B and C

The possible combinations are: A, B, C, AB, AC, BC

These are 6 codes and we need 12 so lets try more A, B, C and D

The possible combinations are: A, B, C, D, AB, AC, AD, BC, BD, CD

These are 10 codes and we need 12 so lets try more A, B, C, D and E

The possible combinations are:

A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE

Finally we got 15 distinct codes which are more than 12 so the least number of letters needed are 5.

Using formula:

Four letters = 4C1 + 4C2 = 4 + 6 = 10

Five letters = 5C1 + 5C2 = 5 + 10 = 15
