How can I read in a txt file in Java?

Question

So, I have a txt file with a varying number of lines, and I want to read in the txt file in an array of strings and have each line as one element of that array. This is what it looks like so far:
In order to find the mistake, I wanted to program to print out something in a various number of places, so I know that the problem is that my program is stuck in an infinite while loop. How can I tell the program to store each line as a string but to stop trying to store things when there are no more lines in the document?

Any help would be very much appreciated! :)

import java.io.BufferedReader;
import java.io.FileReader;

public class Verteilen {

public static void main(String[] args){
FileReader fr= new FileReader ("file.txt");
BufferedReader br= new BufferedReader (fr);
try {
int numLines = 0; //number of lines in txt file
System.out.print(numLines);//just trying to find the mistake

while (line != null) {
++numLines;
System.out.print(numLines);
}
String[] text = new String[numLines];
for (int i=0; i<=numLines; i++) {
text[i]=br.readLine();
}
System.out.print(text[0]); //I just want to see if it works

} finally {
br.close();
System.out.print("file cannot be read");
}

}

}

The line where it says while (line != null), where is declaration of that variable named line, you did not declare it, hence the error.
