Java threads locking on a specific object

Question

I have a web application and I am using Oracle database and I have a method basically like this:

public static void saveSomethingImportantToDataBase(Object t         


        

Answer 1

public static void saveSomethingImportantToDataBase(Object theObjectIwantToSave) {
  synchronized (theObjectIwantToSave) {

      if (!methodThatChecksThatObjectAlreadyExists) {
         storemyObject() //pseudo code
      }
 // Have to do a lot other saving stuff, because it either saves everything or nothing
      commit() // pseudo code to actually commit all my changes to the database.
  }
}

The synchronized keyword locks the object you want so that no other method could access it.
