FAQs

Is Scala java based?

  • Yes, Scala is Java-based in several ways. It runs on the Java Virtual Machine (JVM), allowing it to interoperate with Java code seamlessly. Scala can call Java libraries, and Java programs can also invoke Scala code. Additionally, Scala’s syntax and design were influenced by Java, though it provides more concise and expressive features, such as functional programming support and better handling of concurrent programming.
  • So while Scala is not a direct extension of Java, it is deeply integrated into the Java ecosystem.

Is Spark java based?

  • Yes, Apache Spark is primarily written in Scala, which runs on the Java Virtual Machine (JVM). However, since Scala is compatible with Java, Spark can be considered Java-based to a degree.

Key Points

  • Core Language: Spark’s core is written in Scala, which is a JVM language.
  • Java Integration: Spark can be used with Java due to JVM compatibility. Many Spark components are accessible through Java APIs.

  • Other Supported Languages: Besides Scala and Java, Spark also supports Python (through PySpark) and R for data processing.

  • In summary, while Spark is not “Java-based” in the strictest sense, it is built on the JVM, allowing Java to be a supported language for Spark applications.
