arrange(java.lang.String[][]) in Test cannot be applied to (java.lang.String) arrange

Hi, I am not able to pass a 2d array of string.

error msg shown:
arrange(java.lang.String[][]) in Test cannot be applied to (java.lang.String) arrange(arr[12][5]);



import java.lang.*;
import java.io.*;

public class Test {

static int count;
static String[][] arr=new String[12][5];

String[] lines = new String[0];

try {
File file = new File(path);
br = new BufferedReader(
new InputStreamReader(
new FileInputStream(file)));
String line;

while( (line = br.readLine()) != null ) {


print(line);


}
br.close();

} catch(IOException e) {

System.out.print(arr[x][y]+" ");
}
System.out.print("\n");

}

String data=data1.replaceAll("\\b\\s{2,}\\b", " "); // replace multiple spaces by a single space between words

String[] words = data.split("\\s"); //words is an array of splitted words in a line(1 space considered as 1 word)


for(int j = 0; j < words.length; j++)
{ arr[count][j]=words[j];
// System.out.print(arr[count][j]);
}//word.length gives no. of words in a line.
count++;

Hi, I am not able to pass a 2d array of string.

error msg shown:

Read what the compiler is complaining about: it found a method 'arrange' that needs a two dimensional array of Strings as its parameter but you are trying to call it with a single String as a parameter:

        arrange(arr[12][5]); // <-- here

Of course that doesn't work; supply a two dimensional array as a parameter, not just one String element.

kind regards,

but as I understand I am using arr[12][5] as a 2D string array, in which I had stored data from the file and then passing it to another method arrange(String[][] arr1).
I am not able to understand , what exactly I am missing?

[JavaHater]

pass in the array

arrange(arr);

because you have defined your function to take in a 2D string array , as in

public static void arrange(String[][] arr1)

if you do this

arrange(arr[12][5]);

you are passing in a string that is contained in row 11 item 6 of arr array, which is wrong.

Thanx ... It worked.
