If a referenced object changes, the changes are visible to both … Read more
You are missing brackets around the two lists. The way it was written the dtype argument was receiving the value [79000,3.9,16933.26], which obviously cannot be interpreted as a valid NumPy data type and caused the error.
To start you off on your assignment, String.split splits strings on a regular expression and this expression may be an empty string: Yields the array: Getting rid of the empty 1st entry is left as an exercise for the reader 🙂 Note: In Java 8, the empty first element is no longer included.

Your function declaration and definition are not consistent, you want to generate vector from Initialize, you can do: To print vector: Now you call: Don’t forget to change function definition of Initialize, Print to match the new signature I provided above. Also you are redefining a local variable v which shadows function parameter, you just … Read more
