Yesterday we try to write the .properties file.
Java – Write .properties

But most of the time we would like to read them file instead. The following Class demonstrate how to write the config.properties.

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;

public class ReadPropertyFile {
  public static void main(String[] args) {
    Properties prop = new Properties();
  	 
    try {
      // Load the property file
      prop.load(new FileInputStream("src/main/resources/config.properties"));

      // Get and print the values
      System.out.println(prop.getProperty("name"));
      System.out.println(prop.getProperty("url"));
    } catch (IOException ex) {
      ex.printStackTrace();
    }
  }
}

This is the src/main/resources/config.properties.
