Reading from a file, multiple lines

This isn't homework, I'm only in 8th grade my school doesn't have java courses before you ask)<--
Well I ran into a funny little problem, not quite sure how I should approach it;
Well I have a file looking like this:
1 0 3 2
2 3 4 5

And so on going down like 20 lines.
Here is my code:
It is meant to read the file, and to test it I had it print out the lines, but it only prints out the first line of the file.
I know that my method readLine(); reads the first line only, how would I get it to read the next line?

Code :

---

public class getNumbersFromFile
{
	public static void main(String[] args) {
		getNumbersFromFile file = new getNumbersFromFile();
 	file.getFileFromMethod();
 
	}
	public void getFileFromMethod(){
 
try {
 
 
			BufferedReader FileReader = new BufferedReader(new FileReader("SudokuBoard.txt"));
			String Text = FileReader.readLine();
 
			String[] Split = Text.split(" ");
			System.out.println(Text);
 
 
			} catch (IOException e) {
				System.out.println("Some sort of interruption.");
				System.out.println(e);
			}
 
		}
}

if u want to display all lines of txt change this

Code :

---

String[] Split = Text.split(" ");
System.out.println(Text);

---

to this

Code :

---

String[] Split = Text.split(" ");
int count = 0
while ( Split[count] != null ) {
System.out.println(Split[count]);
count = count + 1
}

---

that should work i think
but the main problem from what i got was that u were displaying text, not the Split array

I did that;
What i get as output,then error:
0
0
0
0
6
0
0
0
9
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 9
at getNumbersFromFile.getFileFromMethod(getNumbersFro mFile.java:25)
at getNumbersFromFile.main(getNumbersFromFile.java:10 )

Here is a snippet of code to read a file, line by line.

Code :

---

    public static void main(String[] args) throws Exception {
        final BufferedReader bufferedReader = new BufferedReader(new FileReader("SudokuBoard.txt"));
 
        if (bufferedReader != null) {
            String line;
 
           // Keep on looping while line is not null, readLine will return null when it reaches the end of the file and the loop will stop.
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(line);
            }
 
            bufferedReader.close();
        }
 
    }

            bufferedReader.close();
        }
 
    }
