LESSON 5.9

Strings Can Be Shared

A String is a reference too: two variables can share the same text, so changing one character appears in both. clone() creates a separate string.

Goal Predict what the program prints.

Write a Zirk program, then run it to see the world react.

Predict the program output hello Hello Jello Hello Hello Jello hello hello Jello
