Hello. I am having problems getting my program to compile. I am getting 1 error message: 'class' or 'interface' expected
class Cube1{}{
Could anyone please offer some suggestions. Thanks.
Here is my code:
// This class name is Cube1
public class Assignment6_5 {
public static void main(String[] args) {
Cube1 cube = new Cube1();
double newWidth = (1.0);
double newHeight = (1.0);
double newLength = (1.0);
String newColor = ("white");
class Cube1{}{

private double width = 1.0;

private double height = 1.0;

private double length = 1.0;

private static String color = "white";
public Cube1(){}{

public Cube1(String newColor){}{
this.color = new color;

public Cube1(double newWidth, double newHeight, double newLength){}
this.Width = newwidth;
this.Height = newHeight;
this.Length = newLength;
public Cube1(double newWidth, double newHeight, double newLength, String newColor){}
this.Width = newWidth;
this.Height = newHeight;
this.Length = newLength:
this.Color = newColor;
public double getVolume(){}{
return Volume;
public double getWidth(){}{
return Width;
public double getHeight(){}{
return Height;
public double getLength(){}{
return Length;
public String getColor(){}{
return Color;

why do you have class Cude1{} in this way?

In many places in this code, you have got a set of empty "{}" braces. In every case, it's incorrect syntax. Not sure what you're going for with that -- can you explain it to us?

Your code in code tags with errors highlighted:

Your code with syntax corrected and formatted:
Notice the extra curly braces are gone, and how much more readable it looks.

More errors. this.Width instead of this.width, this.Height instead of this.height.....and many more.
Hopefully this will compile. But.. the purpose?

Thanks everyone for you help. Sorry, I am new to Java and still trying to learn the concepts. Again, I really appreciate everyone's help. Thanks again. This has really been a great help.
It is sorta covered in the JavaRanch Style Guide.
