QUESTION 2:
Class Rectangle has two data members, length (type of float) and width (type of float).
The class Rectangle also has the following:
//mutator methods
void setlength (float len)
}
//B.
length = len;
H
accessor methods
float getLength()
I
return length;
The following statement creates an array of Rectangle with size 2:
Rectangle[] arrayRectangle= new Rectangle[2];
Is it correct if executing the following statements? What is the output? If it is not correct, write the correct one
arrayRectangle. setLength (12.59);
System.out.printin[rectangle Set.getLength());
arrayRectangle[1].setLength(4.15);
System.out.println(arrayRectangle[1].getLength()):
QUESTION 3:
Use the following int array
int[] numbers = { 42, 28, 36, 72, 17, 25, 81, 65, 23, 58}
-Open file data.txt to write.
to write the values of the array numbers to the file with the
y numbers to get the values
