Imagine Vanya, Mira, and Akhil are working together on a Java program for their school project. They are having a blast, but suddenly they hit a roadblock. They try to access an index in an array that doesn't exist. Oops! What exception will Java throw in this fun-filled coding adventure?

• ArrayIndexOutOfBoundsException

• NullPointerException

• IndexOutOfBoundsException

• IllegalArgumentException

Aanya, Mira, and Prisha are having a fun coding session on Java. Suddenly, they stumble upon a concept called 'anonymous array'. Aanya believes it's an array without any elements, Mira thinks it's an array without a name, and Prisha is of the opinion that it's an array with a single element. Can you help them figure out who is correct?

• Aanya: An array without any elements

• Mira: An array without a name

• Prisha: An array with a single element

• None of them

Imagine Nikita, Aashi, and Anika are working together on a massive Java project. They need to store a colossal amount of data in a single variable and are considering using an array. Can you guess one advantage they would get if they use an array in their Java project?

• It would turn their code into a super-efficient machine

• It would magically allow for dynamic size

• It would grant them the power of random access

• It would automatically manage memory like a pro

Imagine Nikita, Dia and Kabir are working together on a thrilling Java project. They are in a situation where they need to store a wild mix of data like integers, strings, and booleans all in a single array. Is this possible in Java?

• Yes, absolutely!

• No, not at all.

• Only if the data types are having a party together.

• Only if the array is declared as an Object, the master of all.
