Solution

This is a Java program that demonstrates the use of a generic method. Here's a step-by-step explanation:

  1. The class Test is defined.

  2. Inside the Test class, a static generic method named genericDisplay is defined. This method takes a single argument of any type (denoted by <T>), and it prints the class name of the argument along with the argument itself.

  3. The main method is defined. This is the entry point of the Java program.

  4. Inside the main method, the genericDisplay method is called three times with different types of arguments: an Integer, a String,
