Which variables should you use to declare the class Hexagon. Hexagon is drawable and it has several vertices, Colors that can be stored by a Vector and a flag of boolean type. What can you use to declare the member variables of this class?
A. Object
B. boolean
C. Vertice
D. Vector
E. Hexagon
Since none of the modifiers are we assume that we have to specify the modifier(public) as a part of declaration?
Should it be
public class Hexagon extends drawable(vertice integer, flag boolean, color vector){}
Now, 1. I have used a lot of words not given. Is that right?
2. What is the correct answer?
3. Should {} be used while decalaring a class?

A panel has grid layout with 2 rows and 2 columns. there is a button in each cell and another button is added to the pnale as follows:-
aPanel.addbutton(new button("Bob")). Where will the new button be placed?
A. row1 col3

It sure doesn help!!! thanks!!! But I have another small question. Since equals(0 acts the same way as == in StringBuffer. does that mean that if
String Buffer s1= new String Buffer("10");
String Buffer s2= new String Buffer("10");
then would s1.equals(s2) return false???
Could somebody explain to me what happens when "==" and "equals()" is applied to wrapper classes and also String Buffer) ??
like for eg:
Integer ai= "10";
Integer bi = "10";
what will be the result of :
1. ai==bi
2. ai.equals(bi)
3. What if the word "new" was added in their declaration/initialization?
4. How different is it for String Buffer?
5. How different is it for primitive data types?

Thanks Vani...that helps!!!
Please help me. I think the right answer is D as it is post-increment. But the right answer is B. Why???
What is the output of the following code:-
int x=4;
int y=7;
while(x++<5 && y++<8){
System.out.println("x=" +x +" y=" +y);
A. x=5 y=8
B. x=6 y=8
C. x=6 y=9
D. x=4 y=7
Which of the given options are true about the rectangle drawn by the following code ?
A. rectangle is a square
B. width=200 pixels
C. width=170 pixels
D. bottom right corner x=200,y=200
E. bottom right corner x=230,y=230
The answer given for this question was A,B,E. I think just A,B. I think the bottom right corner is x=230,y=30. Could somebody explain why E is also right.
