Answer 1

Hmmm! The 'var' keyword appears to be specific to Java 10. Code Playground probably runs below that (supposingly Java 8, if not 9). Good to know.

Answer 2

Change 'var' to 'String[]'

Answer 3

oh right! thanks for clarifying.

Answer 4

thanks! it worked. but why did it not work like it did on the laptop? and how do I print out the output in ascending order
