What do the following print?

In this code, the class Main contains both an instance variable instanceVar and a static variable staticVar. The sequence of initialization and execution is as follows:

Static Variable Initialization:

staticVar is declared and initialized to 666.

Static Block Execution:

The static block executes, updating staticVar to 42.

Instance Variable Initialization:

When a new instance of Main is created, instanceVar is initialized to the current value of staticVar, which is 42.

main Method Execution:

The main method creates a new instance of Main and prints the values of instanceVar and staticVar.

Therefore, the output of the program is 42 42.
