Getting Objects from a PropertyResourceBundle Instance from ByteStream Example

The following example shows the usage of Java PropertyResourceBundle handleGetObject() method. We created a InputStream of given content and then using that stream a PropertyResourceBundle object is created. Then using handleGetObject() method, we're getting all the resources and then values are printed.

package com.tutorialspoint;

import java.io.IOException;
import java.io.InputStream;
import java.io.StringBufferInputStream;
import java.util.PropertyResourceBundle;

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

      // Prepare content for simulating property files
      String fileContent = 
         "# Integer value 1\n" +
         "s1 = 1\n" +
         "# String value PropertyResourceBundleDemo\n" +
         "s2 = PropertyResourceBundleDemo\n" +
         "# Date value Fri Jan 31 00:00:00 IST 3913\n" +
         "s3 = Fri Jan 31 00:00:00 IST 3913";
      InputStream propStream = new StringBufferInputStream(fileContent);
         
      try {

         // Create property resource bundle
         PropertyResourceBundle bundle = 
         new PropertyResourceBundle(propStream);

         // Get resources
         Object res1 = bundle.handleGetObject("s1");
         Object res2 = bundle.handleGetObject("s2");
         Object res3 = bundle.handleGetObject("s3");

         // Print resource contents
         System.out.println("[Resource1] "+res1);
         System.out.println("[Resource2] "+res2);
         System.out.println("[Resource3] "+res3);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

[Resource1] 1
[Resource2] PropertyResourceBundleDemo
[Resource3] Fri Jan 31 00:00:00 IST 3913

Getting Objects from a PropertyResourceBundle Instance from StringReader Example

The following example shows the usage of Java PropertyResourceBundle handleGetObject() method. We created a InputStream of given content and then using that stream a PropertyResourceBundle object is created. Then using handleGetObject() method, we're getting all the resources and then values are printed.

package com.tutorialspoint;

import java.io.IOException;
import java.io.StringReader;
import java.util.PropertyResourceBundle;

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

      // Prepare content for simulating property files
      String fileContent = 
         "# Integer value 1\n" +
         "s1 = 1\n" +
         "# String value PropertyResourceBundleDemo\n" +
         "s2 = PropertyResourceBundleDemo\n" +
         "# Date value Fri Jan 31 00:00:00 IST 3913\n" +
         "s3 = Fri Jan 31 00:00:00 IST 3913";
      StringReader reader = new StringReader(fileContent);

      try {
      
         // Create property resource bundle
         PropertyResourceBundle bundle = 
         new PropertyResourceBundle(reader);

         // Get resources
         Object res1 = bundle.handleGetObject("s1");
         Object res2 = bundle.handleGetObject("s2");
         Object res3 = bundle.handleGetObject("s3");

         // Print resource contents
         System.out.println("[Resource1] "+res1);
         System.out.println("[Resource2] "+res2);
         System.out.println("[Resource3] "+res3);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

[Resource1] 1
[Resource2] PropertyResourceBundleDemo
[Resource3] Fri Jan 31 00:00:00 IST 3913
