Solution
The output of the code will be "10".
Here's the step by step explanation:
- The code defines a class named Test.
- Inside the Test class, there is a main method which is the entry point of any Java application.
- Inside the main method, an integer variable x is declared and initialized with the value 10.
- The System.out.print(x + " ") statement prints the value of x followed by a space. So, "10 " is printed.
- There is also a static block in the code which is a block of code that is run when the class is loaded into memory. However, this static block is never executed because it is placed after the main method. In Java, static blocks are executed when the class is loaded into memory, which happens before the main method is called. But if the static block is placed after the main method, it will not be executed.
- So, the output of the code is "10", not "10 20" or "20 10".
