Default values
In this task, you need to create 7 public fields for a class. Be sure they are initialized with default values (int intVar, double doubleVar, Double DoubleVar, boolean booleanVar, Object ObjectVar, Exception ExceptionVar, and String StringVar). In the main method, display their values in the specified order.

Static modifiers and kittens
Let's introduce cats to the world of static blocks. First, in the Solution class, we'll create a Cat class with a public String field name, but without a constructor with parameters. Then in a static block, we'll create a Cat object and display the created cat's name on the screen.
