  • Capitalization Errors while Java Programming This is one of the most frequent errors that we all make. It’s so simple to do, and sometimes one can look at an uncapitalized variable or method and still not spot the problem. I myself have often been puzzled by these errors, because I recognize that the method or...

  • Java Class for Sending Email using Java API Introduction This is a java class file for sending mails using java APIs. It requires two jar files to be set in the class path. Also Java J2SDK is required to compile or run this code. A valid SMTP server ip is required and that should be authenticated by a...
  • Preventing concurrent access to shared variables by threads in Java Programming When writing multi-threaded applications, many programmers (myself included) often cut corners, and leave their applications and applets vulnerable to thread conflicts. When two or more threads access the same data concurrently, there exists the possibility (and Murphy’s law holding, the probability) that two threads will access or modify the same...

  • Pass by Value and Pass by Reference in Java This can be a frustrating problem to diagnose, because when you look at the code, you might be sure that its passing by reference, but find that its actually being passed by value. Java uses both, so you need to understand when you’re passing by value, and when you’re passing...
  • Inbuilt Functions in Oracle Character Functions in oracle String function plays important role in oracle as often it is required to convert the string or extract certain part of it. These functions accept column value or an expression as the input. ASCII This function is used to get the ASCII value of a character....

  • Oracle PL/SQL: Is Null / Is Not Null In other languages, a null value is found using the = null syntax. However in PLSQL to check if a value is null, you must use the "IS NULL" syntax. To check for equality on a null value, you must use "IS NULL". For example, IF Lvalue IS NULL then...
