from file to array java code example

Example 1: from file to array java

BufferedReader abc = new BufferedReader(new FileReader(myfile));
List lines = new ArrayList();

while((String line = abc.readLine()) != null) {
    lines.add(line);
    System.out.println(data);
}
abc.close();

// If you want to convert to a String[]
String[] data = lines.toArray(new String[]{});

Example 2: from file to array java

BufferedReader bufferedReader = new BufferedReader(new FileReader(myfile));
String []data;
data = new String[10]; // <= how can I do that? data = new String[lines.size]

for (int i=0; i

ArrayList result = new ArrayList<>();
 
try (BufferedReader br = new BufferedReader(new FileReader(filename))) {
    while (br.ready()) {
        result.add(br.readLine());
    }
