QUESTION 1:
Look at the following array declaration:
Int[ ] numbers = { 4, 7, 3, 6, 8, 9};
What is the output of the following lines?
//A.
System.out.println(numbers[3]);
//B.
x = 2 * numbers[2] + numbers[4];
System.out.println(x);
//C.
x = 3 + numbers[3]++;
System.out.println(x);
QUESTION 2:
Class Rectangle has two data members, length (type of float) andwidth (type of float).
The class Rectangle also has the following:
//mutator methods
void setLength (floatlen)
{
length =len;
}
//accessor methods
float getLength ()
{
return length;
}
The following statementcreates an array of Rectangle with size 2 :
Rectangle[ ] arrayRectangle=new Rectangle[2];
Is it correct if executing the following statements? What is theoutput? If it is not correct, write the correct one
//A.
arrayRectangle. setLength(12.59);
System.out.println(rectangleSet.getLength());
//B.
arrayRectangle[1].setLength(4.15);
System.out.println(arrayRectangle[1].getLength()):
QUESTION 3:
