i want to ask if there is a way to store or write multiple lines of String array in a file from console. For example:
John 19 California
Justin 20 LA
Helena 10 NY
I just want to get some idea on how to do it using FileWriter or PrintWriter or anything related t this problem.
If you're using Java 7, you could use the Files.write method.
Here's an example:
public class Test {
public static void main(String[] args) throws IOException {
String[] arr = {"John 19 California",
"Justin 20 LA",
"Helena 10 NY"};
Path p = Files.write(new File("content.txt").toPath(),
Arrays.asList(arr),
StandardCharsets.UTF_8);
System.out.println("Wrote content to "+p);
}
}
Yes, go through all the Strings in your array and write them to the desired file using FileWriter.
String[] strings = { "John 19 California",
"Justin 20 LA",
"Helena 10 NY" };
BufferedWriter bw = new BufferedWriter(new FileWriter("/your/file/path/foo.txt"));
for (String string : strings) {
bw.write(string);
bw.newLine();
}
bw.close();
List<String>, then dump the content into a file. To resolve a problem, split it into smaller problems and solve each problem at a time.
