Can a method throw java.lang.Exception without declaring it in java?
No, for that matter to throw any exception explicitly you need to create an object of that exception and throw it using the throw keyword.
Without creating an object you cannot throw an exception explicitly, you might create a scenario that causes the respective exception.
Example
Following Java program throws a NullPointerException
public class ExceptionExample {
public static void main(String[] args) {
System.out.println("Hello");
NullPointerException nullPointer = new NullPointerException();
throw nullPointer;
}
}Output
Hello Exception in thread "main" java.lang.NullPointerException at MyPackage.ExceptionExample.main(ExceptionExample.java:6)
