Create a Scatterplot visualization that reads data from a comma-separated text file. The visualization code should be written in Java using Processing.


Object-Oriented. Build a class entitled ScatterPlotPoint that stores all of the visual dimensions of an individual point and plots it on the screen.
Each plotted point will be an instance of this class.
Multiple visual attributes are supported:
Plot mark along the X Axis
Plot mark along the Y Axis
Color of the mark
Size of the mark
Either shape or orientation of the mark
Automatic scaling. The Plot should be automatically sized on the basis of the variables that are assigned to the X and Y dimensions.
Grid Marking. The axes should have tick marks appropriate to the X and Y values to mark regular data intervals.
Variable Assignment. Data Variables can be assigned to any of the different visual attributes.
Interaction. There must be a combobox that assigns data

OK so I'm relatively new to java, and I am trying to create a simple program in which it stores data about an animal, and then displays that data in viewable format. This is what I have to far.

public class HomeProject1a{
public static void main (String [] args){
String name = "Human";
int numLegs = 2;
double height = 1.8;
boolean hasTail = false;

System.out.println("The animal is a " + name);
System.out.println("A " + name + " has " + numLegs + " legs");
System.out.println("A " + name + " is " + height + " meters tall");
if (hasTail = true) System.out.println("A " + name + " has a tail");
else if (hasTail = false) System.out.println("A " + name + " doesn't have a tail");

the problem is the if and else if statements. I do not know how to make java recognise them as if statements, and if I run the program, this is the output:

The animal is a Human
A Human has 2 legs
A Human is 1.8 meters tall
A Human has a tail

any help?

please, explain these to me using simple english.

I am new to JAVA ! When I am going to write a program , how can I decide how many Class I have to create ? And how can I know what members , method in each class ? What the purpose of MAIN CLASS How can Classes as well as methods connected to run my program ? With C++ before , I usually write code only on one main screen with all variables together. Thank you

you have a single aircraft with 40 which flies between New York and London. the first 10 seats a first class while the rest are economy. passengers are required to make bookings for their flights. seats can be reserved and unavailable when paid for. implement the plane as a linked list of seats nodes, in java. seats can be added or removed from the plane as desired. this plane can then be checked if it is empty or full when making a reservation for a customer or if there is a desired seat available. implement an appropriate interface the user or clerk will be using to make these reservations. a reservation should have the traveler's details and the seats reserved and this information needs to be stored persistently. you are required to use a database. i just need the help with communicating with the database. just the explanation please .

Assume there is a triangle shape as..

(0,0)
(1,0) (1,1)
(2,0) (2,1) (2,2)
(3,0) (3,1) (3,2) (3,3)
(4,0) (4,1) (4,2) (4,3) (4,4)


So If I receive integers like
1 2 3

I want to store as 1 as

row[0] = 0;
col[0] = 0;

and 2 as


row[1] = 1;
col[1] = 0;

3 as follow.
row[2] = 1;
col[2] = 1;

public class Test {
public static void main(String[] args) {
int i, j;
for(i = 0; i < 5; i++) {
for(j = 0; j <= i; j++)
System.out.printf("(%d,%d)", i, j);
System.out.println();
}
}
}
