Read file to create a matrix

[Miles Runner]

Hello,
I want to read a file to create a two-dimensional array and store the size of this table. I created a class matrix. In another method constMat class.
I am getting any error in my code, this is my code, please have a look at it.

Public static Matrix ConstMat(String path){
			int t =0;
			
			int s =0;
BufferedReader file;
			try {
				file = new BufferedReader(new FileReader(path));
				try {
					String ln1;
ln1 = file.readln();
s = Integer.function valueOf() {
    [native code]
}(ln1);
Matrix m1 = new Matrix(s);
					while(file.read()!=-1){
						
						if(Turn! =0){
							int i =0;
String ln;
ln = file.readln();
StringTokenizer st = new StringTokenizer(row," ");
							while (st.hasMoreTokens()){
								int con;
con = Integer.function valueOf() {
    [native code]
}(st.nextToken());
m1.SetCell(con, t, i);
i + +;
							}
						t + +;
						}
						
					}
					
				} catch (NumberFormException e) {
					e.printStackTrace();
				} catch (IOException e) {
					e.printStackTrace();
				}
				
			} catch (FileNotFoundException e) {
				e.printStackTrace();
			}   
			ret m1;
			
	}

Hello,
I have not clearly understood what exactly are you trying to do here. But my suggestion for you is

if(Turn! =0)

because then I do not see how he does not go on indefinitely complete turn = 0. If you need more information on array and two dimensional arrays and how to handle them in java then you can visit the sun's official site. Best of Luck

Hello,
you must define your matrix before you are doing the rest. I mean to say, take a look at the example below

Public static Matrix ConstMat(String path){
			int con =0;
			int s =0;
BufferedReader file;
                        Matrix m1

You are doing this exactly reverse and that is why I think you are getting an error. If you fix it then I think the error will be removed and your code will compile successfully.

Hello,
This is my matrix class, please check and if you find any problem in the clas then please guide me with the correct one.

Public class Matrix {
	int tmp;
	int[][] mt;
	Public Matrix(int s){
		tmp = s;
mt =new int[s][s];
	}
	Public void SetCell(int val, int row, int Pass){
		mt[row][Pass]= val;
	}
}

Hello,
I think you can do it also with the ListIterator , though I am not sure of this because I have not tried it. Just have a look at the code and if you need then use it.

 ListIterator  li = list.listIterator ();
	  Object [] barr = new Object[i];
	  String [] str = new String[i];
 
	   while (li.hasNext()) {
	   barr[counter]=li.next();
	   str[counter]=barr[counter].toString();
 
           counter++;
        }

Hello,
For creating a matrix you need to use the two dimensional array in your program and here is the example of the two dimensional array in java

int[][] t;
 t = new int[10][];  // allocate array of rows
 for (int r=0; r<t.length; r++) {
     t[r] = new int[r+1];
 }
 
 // print the tangular array (same as above really)
 for (int r=0; r<t.length; r++) {
     for (int c=0; c<t[r].length; c++) {
         System.out.print(" " + t[r][c]);
     }
     System.out.println("");
 }
