The SocketException is an exception in Java that is thrown to indicate that an error was encountered while creating or accessing a Socket. Since the SocketException is a checked exception, it either needs to be thrown or surrounded by a try-catch block in code.

The UnknownHostException is an exception in Java that is thrown to indicate that the IP address of a host could not be determined. Since the UnknownHostException is a checked exception, it either needs to be thrown or surrounded by a try-catch block in code.

Under certain conditions, custom exceptions that are not predefined in C++ may be useful to generate. In C++, any type can be caught or thrown that matches some requirements. These are that the type should have a valid copy constructor and destructor. Custom exceptions provide relevant information about an error to the exception handling mechanism.

The CloneNotSupportedException is an exception in Java that is thrown to indicate that the clone() method in class Object was called to clone an object, but that object's class does not implement the Cloneable interface. Applications that override the clone() method can also throw this exception to indicate that an object could not or should not be cloned.

The InstantiationException is a runtime exception in Java that occurs when an application attempts to create an instance of a class using the Class.newInstance() method, but the specified class object cannot be instantiated. Since the InstantiationException is an unchecked exception, it does not need to be declared in the throws clause of a method or constructor.

The EmptyStackException is a runtime exception in Java that is thrown by methods in the Stack class to indicate that the stack is empty. Since the EmptyStackException is an unchecked exception, it does not need to be declared in the throws clause of a method or constructor.

Development time is precious. Developers are highly-skilled and highly-paid, and so naturally you want to make sure that they are as productive as possible. Many organizations are starting to hire Developer Experience Engineers to make sure that their developers are using the best tools and processes possible. To make developers more productive, the first step is to figure out exactly what developers are actually doing. Then, we need to figure out what we want them to do.

The NoSuchFieldError is an error in Java that occurs when a specified field does not exist. It is thrown when an application attempts to access or modify a field of an object or a static field of a class but the object or class no longer contains that field. The NoSuchFieldError only occurs during runtime if the definition of a class has changed incompatibly. Since it is thrown at runtime, it does not need to be declared in the throws clause of a method or constructor.

The unsupported major.minor version error is thrown in Java when a class is compiled using a higher version of the Java Development Kit (JDK) but executed on a lower version of the Java Runtime Environment (JRE). The exact cause is printed on the version e.g. in the case of major.minor version 52.0, the class is compiled using JDK 8 since major version 52 corresponds to Java SE 8. This error can usually be fixed by running the application on the same (or higher) JRE version as the JDK.

The SecurityException is a runtime exception in Java that is thrown by the security manager to indicate a security violation. The SecurityException is an unchecked exception and does not need to be declared in the throws clause of a method or constructor.
