In order to read a file from the resources folder make use of the getResourceAsStream method from the ClassLoader class,
Example:import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.nio.charset.StandardCharsets;
/**
*
* Read file from the resources folder
* using Java code.
*
*/
public class Main {
public static void main(String[] args) throws IOException {
String fileName="resource.properties";
String line;
ClassLoader classLoader = Main.class.getClassLoader();
InputStream inputStream = classLoader.getResourceAsStream(fileName);
if(inputStream == null) {
throw new IOException(fileName + " file not found!");
}
InputStreamReader streamReader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
BufferedReader bufferedReader = new BufferedReader(streamReader);
while ((line = bufferedReader.readLine()) != null) {
String[] element = line.split("\\=");
System.out.println("Key: " + element[0]+" , Value: " +element[1]);
}
}
}
Output:
Key: name , Value: code2care
Key: username , Value: admin
Key: password , Value: 123456
You will receive a IOException if the file is not found.
