How To Read boolean value from a property file

[Ramakanta Sahoo]

Hi All,

I have a small question I have code like below

 
 private boolean doAction = false;
    private boolean isQuiet = false;
    private boolean isNoProgress = false; 
    private boolean isForce = false; 
   

I want to read the values like true or false from a property file named input.properties instead of hard coding it . How to do it . Can somebody shed some light am confused.

Take a look at Boolean.parseBoolean()!

I am getting a error of

Code:

 
 ResourceBundle bundle = ResourceBundle.getBundle("inputs");
        String TransferFilesOnly = bundle.getString("TransferFilesOnly");
        String SummaryOfActionsOnly = bundle.getString("SummaryOfActionsOnly").trim();
--------------
------------------
 private boolean doAction = Boolean.getBoolean(TransferFilesOnly); 
    private boolean isQuiet = Boolean.getBoolean(SummaryOfActionsOnly);
----------------

Executing as java -classpath ./inputs.properties -jar ./myTool.jar blah blah

Please help.

doAction = "true".equals(yourProperties.getProperty("doaction"));
isQuiet = "true".equals(yourProperties.getProperty("isquiet"));

What Do you mean by this. Can you please make me understand with some example.

[Zandis Murāns]

Yeah, sure.

Create properties file, for example c:\my.properties
In this file define some properties, for example

doaction=true
isquiet=false

next, in your java code, create instance of java.utils.Properties class:

java.utils.Properties p =  new java.utils.Properties();

fulfil this object with your properties:

try {
    p.load(new java.io.FileInputStream("c:\\my.properties"));
}
catch (java.io.IOException e) {
    ; // deal with exception
}

Now assign your variables

doAction = "true".equals(p.getProperty("doaction"));   
isQuiet = "true".equals(p.getProperty("isquiet"));
