BuildProgram exited with code -532462766. When i entered the project again it gave a “Project has compiler errors” message and asked me to use the safe mode, which i refused, and when it finally loaded i saw it: Internal build system error. I searched the name “PlasticSCM” on the project folder and then deleted everything.Īfter doing this it only got worse. I admit that i was dumb, but in my defence i’ll say it was very late, i was sleepy, and very angry that i couldn’t figure out the source of the issue… And since i saw that it was probably caused because of PlasticSCM I did something nobody should ever do: import java.io. 1739×422 835 KBĮverything worked properly, but having 30.000 iterations of an error in console wasn’t pleasent, and definitely should’t be happening, so i tried to investigate using both UnityAnswers and ChatGPT, but i couldn’t find a solution and i was getting mad… It is not allowed to declare parent class exception in the subclass method, we get compile time error if we try to compile that program. import java.io.* Įxample of Subclass overriden method with parent Exception If method of super class declared an exception then it is upto the subclass to declare exception or not. It is optional to declare the exception in sub class during overriding. import java.io.* Įxample of Subclass overriden method with no Exception Method of a sub class can declare same exception as declared in the super class. It means, if Super class method throws object of NullPointerException class, then Subclass method can either throw same exception, or can throw no exception, but it can never throw object of Exception class (parent of NullPointerException class).Įxample of Subclass overriden method with same Exception If Super class method throws an exception, then Subclass overriden method can throw the same exception or no exception, but must not throw parent exception of the exception thrown by Super class method. More about Overriden Methods and Exceptions Void show() throws ArrayIndexOutOfBoundsExceptionīecause ArrayIndexOutOfBoundsException is an unchecked exception hence, overrided show() method can throw it. Unchecked Exceptions are the exception which extend the class RuntimeExeption and are thrown as a result of some runtime error. Method overriding in Subclass with UnChecked Exception If we try to do so, we will get a compile time error. In the example above, the method show() doesn't throw any exception when its declared/defined in the Super class, hence its overridden version in the class Sub also cannot throw any checked exception. Void show() throws IOException //Compile time error Method overriding in Subclass with Checked ExceptionĬhecked exception is the exception which is expected or known to occur at compile time hence they must be handled at compile time. In other scenario, if super class method does not declare any exception, then sub class overriden method cannot declare checked exception but it can declare unchecked exceptions. If super class method declared exception then the method of sub class may declare same exception class, sub exception class or no exception but can not parent of exception class.įor example, if a method of super class declared ArithmeticException then method of subclass may declare ArithmeticException, its subclass or no exception but cannot declare its super/parent class like: Exception class. In this scenario, there can be possible two cases: either method of super class can declare exception or not. There are few things to remember when overriding a method with exception handling because method of super class may have exception declared.
