I am trying to read contents from a file and put it into a 2D array of Object type Box. Its giving me a type error. Can somebody please help me?
import java.io.*;
import java.util.Scanner;
public class Gameboard
{
private Box[][] bx;
public Gameboard (String fileNm)
{
try {
BufferedReader input = new BufferedReader(fileNm);
Scanner lineReader = new Scanner(input.readLine());
while (lineReader.next() != null)
{
bx = new Box[row][col];
for(int i = 0; i < row; i++)
for(int j = 0; j < col; j++)
{
bx[row][col] = lineReader.next(); // the error is here
}
}
}
Yeap the error is expected. In bx[row][col] = lineReader.next();
you attempt to read a value. Scanner#next()
by default returns a String
but you're attempting to store it an array of type Box
.
Instead of doing that you should create a Box object an store it that way. Also, you know that you're not traversing all the rows and cols. bx[row][col]
would mean that you'll be assigning a value to 5,7 (in this example).
