Java: Store text file content line by line into an array
Java Input-Output: Exercise-14 with Solution
Write a Java program to store text file content line by line in an array.
Sample Solution:
Java Code:
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Arrays;
public class Exercise14 {
public static void main(String a[]){
StringBuilder sb = new StringBuilder();
String strLine = "";
List<String> list = new ArrayList<String>();
try {
BufferedReader br = new BufferedReader(new FileReader("/home/students/test.txt"));
while (strLine != null)
{
strLine = br.readLine();
sb.append(strLine);
sb.append(System.lineSeparator());
strLine = br.readLine();
if (strLine==null)
break;
list.add(strLine);
}
System.out.println(Arrays.toString(list.toArray()));
br.close();
} catch (FileNotFoundException e) {
System.err.println("File not found");
} catch (IOException e) {
System.err.println("Unable to read the file.");
}
