    Boolean operators in Java are used to perform logical operations on boolean values. These operators are essential for building complex conditions and making decisions in your code. Java provides three primary boolean operators: AND (&&), OR (||), and NOT (!).

    AND Operator (&&)

    The AND operator returns true if both conditions are true. If either condition is false, the result is false. This operator is useful for combining multiple conditions that must all be true for the overall expression to be true.

    Example:

    int a = 10;
    int b = 20;
    int c = 20;

    if ((a < b) && (b == c)) {
    System.out.println("Both conditions are true");
    } else {
    System.out.println("One or both conditions are false");
    }
    Copied!

    Output:

    Both conditions are true
    Copied!

    In this example, both conditions a < b and b == c are true, so the AND operator returns true.

    OR Operator (||)
