Answer:
Both will compile without any error
Explanation:
Since there was nothing to note we assume that they have no errors in them, we compile each java file by typing javac "name of file.java", javac TestsimpleCircle.java in the case of TestsimpleCircle file, and later go on to type java TestsimpleCircle to see the output. Java files can be compiled either in the console (as done above) or in the development environment like Netbeans where you click the run button and it compiles and run the program for you.
Answer:
A
Explanation:
Option A network congestion is the right answer. When broadcasting is done by the hub then it is very prone to the network congestion as network becomes overload and congestion will occur in the network. Data encryption has nothing to do with hub. Also the other options did not apply to hub. Therefore only option A is the right answer.

' if the rectangles were drawn, they would form one larger rectangle.'
That part of the question I don't get.
To print the location of the Rectangle write a toString method in the
Rectangle class.
When using the System.out.println method the toString method of that
object will be called.
If you have to translate the rectangle only when the
System.out.println() methode is used you should translate the rectangle
object in the toString methode.
So the translate method keeps the translated cordinates, but only
translates the rectangle when the toString is called.
So the to string method would be something like that:
String toString(){
return "X-cord.: "+ (this.X1+this.translatedX) +"-"+
(this.X2+this.translatedX) +"
Y-cord.:"+(this.Y1+this.translatedY)+"-"+(this.Y2++this.translatedY);
}
