Introduction to Booleans

What is a Boolean?

• A Boolean refers to a value that is either true or false.
• Booleans are one of the primitive data types.
• Named after George Boole, an English mathematician, philosopher, and logician.

Example of Boolean in Code

• Example code snippet:

  Boolean isStudent = true;
  System.out.println(isStudent);
  

• This code declares a Boolean named isStudent and sets it to true.
• Prints the value of isStudent, which will be true.

Modifying Boolean Values

• You can change the Boolean value:
  • Set isStudent to false and run the code again.

Naming Conventions for Booleans

• Name Booleans like questions (e.g., isStudent).
• Similar to naming in conditional methods in programming tools like Carol.

Hands-On Practice

• Encourage students to practice using Booleans by declaring their own and modifying values.
