| Garbage collection | The process of clearing unused components in ones program from RAM in programming |
| JDK | Java Development Kit |
| JRE | Java Runtime Environment |
| JVM | Java Virtual Machine |

| Front-end | The development part that the user sees (behaviour, styling, structure) |
| Back-end | The development part that the user don’t see (behind the curtains – DB, system logic, etc.) |
| Variable | “nametags” in programming that represent a slot in RAM to store data/information. |
| Data Type | Different Data Types represent different kinds of data (text, numbers, true/false, lists, etc.) |
| Recursive | A development pattern that make function for example be able to execute a task by calling themselves repeatedly by themselves. |
| Statements | The big building blocks in programming that make up a program. |
| Expressions | The smaller part of Statements that help make your program work. |
