Smalltalk and Java are both object-oriented programming languages.
Comparison chart
 | Java | Smalltalk |
|---|---|---|
| Introduction (from Wikipedia) | Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. | Smalltalk is an object-oriented, dynamically typed, reflective programming language. Smalltalk was created as the language to underpin the "new world" of computing exemplified by "human–computer symbiosis." |
