Read data from properties file in java

Home / Read data from properties file in java

In this tutorial i am going to cover the topic how to read data from properties file in java.

properties file contains data in key and value formate

eg: 

suppose i have a file inside my /src/main/resources folder name first.properties and contains data like

name = javaDream

age = 24

job_profile = software Developer

So if you want to read the data from first.properties then add the following code inside your main method

 

InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream(“first.properties”);
Properties properties = new Properties();
properties.load(inputStream);

//For display name

System.out.println(properties.getProperty(“name “));

//For display Age

System.out.println(properties.getProperty(“age “));

//For display Job Profile

System.out.println(properties.getProperty(“job_profile “));
