Creating a properties file in Java and eclipse

Question

I want to create a config.properties file, in which I want to store all the key and values instead of hard coding them in the Java code.

However, I do not know how t

Answer 1

1. Create a new file from file menu Or press Ctrl+N
2. In place of file name write config.properties then click finish

Then you can add properties your property file like this

dbpassword=password
database=localhost
dbuser=user

Example of loading properties

public class App {
  public static void main(String[] args) {

    Properties prop = new Properties();
    InputStream input = null;

    try {

        input = new FileInputStream("config.properties");

        // load a properties file
        prop.load(input);

        // get the property value and print it out
        System.out.println(prop.getProperty("database"));
        System.out.println(prop.getProperty("dbuser"));
        System.out.println(prop.getProperty("dbpassword"));

    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        if (input != null) {
            try {
                input.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

  }
