Question 1

True or false: You need an active internet connection to use code completion in JetBrains IDEs.

Accepted Answer

False. Local code completion works entirely offline, using static analysis and cached indices. Only AI-powered features require internet.

Question 2

True or false: The local history in JetBrains IDEs can revert a single line of code from a week ago, even if you never committed.

Accepted Answer

True. Local History automatically tracks file changes. By default, it retains history for 5 working days and up to 1000 changes per file, allowing line-level reverts from any saved point within that window without VCS.

Question 3

True or false: JetBrains IDEs cannot run on a Raspberry Pi because they require an x86 processor.

Accepted Answer

False. JetBrains IDEs run on ARM-based systems like Raspberry Pi via the official ARM64 builds or third-party JDK support.

Question 4

True or false: JetBrains IDEs can only debug applications written in the same language as the IDE’s primary focus.

Accepted Answer

False. JetBrains IDEs support multi-language debugging, e.g., debugging JavaScript in IntelliJ IDEA alongside Java, thanks to plugin architecture.

Question 5

True or false: A JetBrains IDE can be used to edit and debug code inside a Docker container without installing anything locally.

Accepted Answer

False. JetBrains Remote Development requires a locally installed thin client (Gateway) or a local IDE to connect to a Docker container. You cannot use it without any local installation.

Question 6

True or false: The 'Postfix Completion' feature in JetBrains IDEs was invented by Microsoft and later copied by JetBrains.

Accepted Answer

False. Postfix Completion was introduced by JetBrains in IntelliJ IDEA 13 (2013). It is a JetBrains original feature, not invented by Microsoft.

Question 7

True or false: JetBrains IDEs include a built-in AI assistant that can generate code from a screenshot of a whiteboard.

Accepted Answer

True. JetBrains AI Assistant can interpret images, including whiteboard sketches, and generate code accordingly.

Question 8

True or false: JetBrains IDEs can run a full Discord bot inside a tool window using the built-in HTTP Client.

Accepted Answer

False. The built-in HTTP Client only sends individual requests (HTTP/WebSocket) for testing. It cannot run a persistent application like a Discord bot, which requires a runtime environment to maintain a connection, process events, and execute code.
