“throw and throws are keywords in Java used for handling exceptions.”<\/p>\n

  1. The throw keyword is used to throw an exception object. It is typically used within a method body to manually throw an exception. When the program reaches the throw statement, it will immediately stop executing and pass the exception object to the caller for handling.<\/li>\n<\/ol>\n

    1. The “throws” keyword is used to declare the exceptions that a method may throw. It is typically placed at the end of a method declaration, informing the caller about the types of exceptions that the method may throw. If a method uses the “throws” keyword in its declaration, the places where the method is called must handle the exceptions appropriately, or else there will be a compilation error.<\/li>\n<\/ol>\n
