How to use AES encryption? If you want to encrypt a text put it in the white textarea above, set the key of the encryption then push the Encrypt button.The result of the encryption will appear in base64 encoded to prevent character encoding problems.If you want to decrypt a text be sure it is in base64 encoded and is encrypted with AES algorithm!Put the encrypted text in the white textarea, set the key and push the Decrypt button. When is helpful to use AES encryption? When you want to encrypt a confidential text into a decryptable format, for example when you need to send sensitive data in e-mail.The decryption of the encrypted text it is possible only if you know the right password. What is AES encryption? AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm.The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen. AES was designed to be efficient in both hardware and software, and supports a block leng...

you can define a context listener within the web.xml: <web-app>     <listener>        <listener-class>com.mypackage.MyServletContextListener</listener-class>     </listener> </web-app> Then implement that class something like: public class MyServletContextListener implements ServletContextListener {     private MyThreadClass myThread = null;     public void contextInitialized(ServletContextEvent sce) {         if ((myThread == null) || (!myThread.isAlive())) {             myThread = new MyThreadClass();             myThread.start();         }     }     public void contextDestroyed(ServletContextEvent sce){         try {             myThread.doShutdown();             myThr...

Integer class does provide lots of unitily methods to be consumed directly Integer decimal1 = 21 ; System.out.println(decimal1 + "=" + Integer.toBinaryString(decimal1)); Integer decimal2 = 302 ; System.out.println(decimal2 + "=" + Integer.toOctalString(decimal2)); Integer decimal3 = 43981 ; System.out.println(decimal3 + "=" + Integer.toHexString(decimal3)); Output: 21 = 10101 302 = 456 43981 = abcd

Use Integer.toString(int input, int radix) to convert from an Integer to any type of base number. Integer decimal1 = 21 ; String binaryNumber = Integer.toString(decimal1, 2 ); System.out.println(decimal1 + " in Base 2 : " + binaryNumber); Integer decimal2 = 302 ; String octalNumber = Integer.toString(decimal2, 8 ); System.out.println(decimal2 + " in Base 8 : " + octalNumber); Integer decimal3 = 43981 ; String hexNumber = Integer.toString(decimal3, 16 ); System.out.println(decimal2 + " in Base 16 : " + hexNumber); Output: 21 in Base 2 : 10101 302 in Base 8 : 456 43981 in Base 16 : abcd

Use Integer.parseInt(String input, int radix) to convert from any type of number to an Integer. String binaryNumber = "10101" ; int decimal1 = Integer.parseInt(binaryNumber, 2 ); System.out.println(binaryNumber + " in Base 10 : " + decimal1); String octalNumber = "456" ; int decimal2 = Integer.parseInt(octalNumber, 8 ); System.out.println(octalNumber + " in Base 10 : " + decimal2); String hexNumber = "ABCD" ; int decimal3 = Integer.parseInt(hexNumber, 16 ); System.out.println(hexNumber + " in Base 10 : " + decimal3); Output: 10101 in Base 10 : 21 456 in Base 10 : 302 ABCD in Base 10 : 43981
