Boolean Expressions Quiz: Test Your Java Skills

📚 Quick Study Guide

• 🔑 A boolean expression evaluates to either true or false.
• ➕ Common boolean operators include: AND (&&), OR (||), and NOT (!).
• 💻 In Java, true and false are keywords.
• 💡 Relational operators (e.g., ==, !=, >, <, >=, <=) produce boolean results.
• 🧮 Operator precedence matters! Use parentheses () to clarify the order of operations.
• 📝 Short-circuiting: In &&, if the left operand is false, the right is not evaluated. In ||, if the left is true, the right is not evaluated.
