What are Spring boot starters and name a few important Spring boot starter dependencies?Starters are a set of convenient dependency descriptors that you can include in your application. It scans the specified packages and registers the annotated classes as beans. Auto-configuration eliminates the need for manual configuration and reduces boilerplate The annotation tells Spring where to look for components (such as controllers, services, and repositories) to be managed by the Spring IoC container. It automatically configures the Spring application based on the classpath dependencies, project settings, and environment. It allows you to define beans and their dependencies using annotations like The annotation enables Spring Boot's auto-configuration mechanism. This is a convenience annotation that is equivalent to declaring below three = + + The annotation indicates that the class contains bean configurations and should be processed by the Spring IoC container. Explain and annotationsThe annotation indicates a configuration class that declares one or more methods and also triggers auto-configuration and component scanning. Spring Boot CLI - The Spring Boot CLI is a command-line tool that you can use if you want to quickly develop a Spring application. Output will be 2 as we did not implement hashcode and equals method in Customer class. Yes, T2 will be able to access m2 as it requires object level lock to access m2 method and T1 thread has taken class level lock.You can read more about Object level lock vs Class level lock. What will happen in case of below program? class A No, T2 will not be able to access m2 as it requires lock to access m2 method which is already taken by T1 thread. Yes, T2 will be able to access m2 as it does not require lock to access m2 method./div> 5. Will T2 be able to access m2 method on the same instance at the same time? package 2blog Īs IOException and Exception are checked exception, so you can not broaden the scope of Exception while method overriding. This will work fine as ArrayIndexOutOfBoundsException and IndexOutOfBoundsException are Runtime exceptions and there is no rule for runtime exceptions while method overriding. Void m1() throws IndexOutOfBoundsException Void m1() throws ArrayIndexOutOfBoundsException There will be compile time error.Even though we are assigning B's object to A's reference we can call only methods which are in A from A's reference.
