Can I work with the values ​​in the text file properties?

For example, read the value and add it to logical operations?

If not, then with what can you read and work with the values ​​in a text file?

Properties props = new Properties(); try { props.load(in); } catch (IOException e1) { e1.printStackTrace(); } String answer = props.getProperty("OTBET"); if(answer == "4") System.out.print("answer = 4");

The problem is that I can not compare, nothing happens!

java:

 Properties properties = new Properties(); properties.load(this.getClass().getResourceAsStream("/propertiesfile.properties")); String str = properties.getProperty("a.string"); //str ="test string from property file"

Property file:

 a.string=test string from property file
