Explanation:
The Rectangle class was not provided in this question but after a quick online search I was able to find the class code. Due to this I was able to create a test code in the main Method of my program to create a Rectangle object and call it's display() method. The Test code and the output can be seen in the attached image below. While the code below is simply the Main Test Program as requested.
class Brainly {
public static void main(String[] args) {
Rectangle rectangle = new Rectangle(20, 8);
rectangle.display();
}
}
An administrator is writing into a database and received an error detailed in the exhibit. The two steps to be taken to resolve this are :
Move the Execute SQL statement to be between Connect and Disconnect. Move the Prompt Message to be before the Disconnect statements.
Explanation:
- Dynamic SQL refers to SQL statements that are generated at run-time.
- To disconnect from a database, in the Database Navigator or Projects view, click the connection and then click the Disconnect button in the toolbar or click Database -> Disconnect on the main menu
- You can also right-click the connection and click Disconnect on the context menu
- The PROMPT command may be used to display messages to the user, perhaps supplying a short summary of what your script is going to accomplish.
- The SQL EXECUTE command executes an SQL command and binds the result to 4D objects (arrays, variables or fields).
- A valid connection must be specified in the current process in order to execute this command. The sqlStatement parameter contains the SQL command to execute.
Answer:
The answer is A
Explanation:
Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution within a short execution time.
From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.
Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.
That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.
Python code:
x=121
x += 9
x *= 2
x -= 4
x >>= 2
x -= 121
