+## Logical Operators
+
+Logical operators combine multiple boolean expressions or values. They return a boolean result (`true` or `false`).
+
+These are the logical operators in Java:
+
+- `&&` Logical AND: Returns true if **both** expressions are `true`.
+- `||` Logical OR: Returns true if **any** expression is `true`.
+- `!` Logical NOT: Reverses the result (`true` → `false`).
+
+```java
+int a = 10;
+int b = 5;
+int c = 20;
+
+System.out.println((a > b) && (a < c));  // true, both conditions are true
+System.out.println((a > b) || (a > c));  // true, one condition is true
+System.out.println(!(a > b));            // false, negates true
+```
