I've changed what I had from before for this portion:



Random r = new Random();
for (float a=r.nextFloat(); x>0.01f; x=r.nextFloat()) // the local variable a is never read
...

I am given an error message at a.append, I've taken in what you've said and changed it to a Float, the a is accepted but the append, now states that it is a float and not a Float, but I changed it to...

Ok, I understand.
I expect my class to plot a random list of numbers of floats given in an array.
I was given FloatListDemo to base my FloatList off of so that they would work together.

I'm...

I don't understand how this will help me understand why the countFloats and append don't work.

Example code using FloatList:



package lab6;

import java.util.Random;

/**
* Demonstrates use of the classes FloatList and ArrayPlot. You need not

package lab6;

import java.sql.Array;
import java.util.Random;

/**
* A list of floats that can grow to be as long as necessary.

Ohh!
I didn't call it into the main of the program, yes?

package lab5;

public class ArrayFirst {

public
static void main(String[] args) {

for (int i=0; i<args.length; ++i)
System.out.println(args[i]);
float[] a = {0.1f, 1.2f, 2.3f, 3.4f};

I actually got it solved, thank you though :D

Hello,

I'm working on a new project about arrays, yay!
I'm given a length of 4 and set that to a.
I'm then suppose to make a different int b = a and make another c = the reverse of b, but I...

Thanks, I'll modify it.

Uh.... I meant for a program....
I have to construct a program for a robot that moves around and its position and battery life are recorded back to the public.

How do you make an object, such as a robot, move from left to right and forward and back?

With copeg's tip,
I'm constructing a robot that has to move from right to left and forward and back.
My...

public class Robot {
public Robot(double x, double y) {
x = 0.0;
y = 0.0;
}

public double getX() {
return X;
}

Hi!
So, I've been working on it and I think I did somethings right...
But now my question, main concern is:

How do I get the robot to turn/move?

Hi!
I'm new to this programming stuff and I'm currently struggling.
I was given a project to construct a Robot with a fully charged battery and to make it move with certain buttons.

I was given...

Hey, I'm Missa.

I'm currently a college student and started taking Java programming concepts this semester.
In the beginning I was doing ok and now I'm struggling very much.
I don't want to drop...
