Local variables unavailable

Hey, I have a problem with an error eclipse gives me while debugging.

Code:

---

                private Matrix coMatrix(int x){
                        rowNum = getRowNum();
                        colNum = getColNum();
                        Matrix coMatrix = new Matrix(rowNum-1, colNum-1);
...

---

It goes into this method and sets rowNum as 3 and colNum as 3.
Then it creates a new Object with the constructor and gives 2 and 2 as parameters.

Here is the constructor code:

Code:

---

                public Matrix(int rowNum, int colNum){
                        m = new double[rowNum][colNum];
                }

---

Now it is supposed to create a 2 dimensional double array with 2 rows and 2 columns.

But here it gives me an error "local variables unavailable" which I don't get.
Can anyone help me?

Thanks in advance.

What is "m"?

You may need to give more code here.

Code:

---

public final class Matrix {
               
                private double[][] m;

---

Given the information as presented above, I have no idea what's wrong.

Hopefully someone else smarter will figure it out, but til then, (as stated above) you may wish to post more code and in fact may wish to post a small compilable program that demonstrates your problem.

Best of luck!

edit: are you using an inner class anywhere here?
edit2: and if you do re-post your code, could you post the actual error message, and indicate by comment where the error is being thrown?

Again, good luck!

make m static. could be why you aren't able to access it.

Heathen! ;)

Ok, I figured it out.
Now I have a new problem

I have folowing method:

Code:

---

public Vector mult(Vector v){
                        rowNum = getRowNum();
                        colNum = getColNum();
                        Vector mult = new Vector(rowNum);
                        for(int i = 0; i < rowNum; i++){
                                for(int j = 0; j < colNum; j++){
                                        mult.v[i]+=m[i][j]*v.get(j);
                                }
                        }
                        return mult;
                }

---

The problem here is that I want to access the variable v from the object mult. This is not possible that way, because the Vector object is in another class and the variable is private.
How do I access it?

Can you please copy/paste that compilation error message verbatim?

kind regards,

I've solved this already, but I have a new problem.

And of course you were going to tell us what the problem and solution were here, right??
