Boolean Type in Java

Overview

In Java, the boolean type is used to represent one of two values: true or false. It is commonly used in decision-making statements and control flow, such as if, while, and for loops.

Characteristics of Boolean Type

Type	Size	Values	Default Value
boolean	1-bit	true or false	false

---

Boolean Operations

boolean value1 = true; // primitive boolean
boolean value2 = false; // primitive boolean

Logical Operators

Operation	Symbol	Description	Example
AND	&&	Returns true if both operands are true.	value1 && value2
OR	||	Returns true if at least one operand is true.	value1 || value2
NOT	!	Reverses the value of the operand.	!value1

Relational Operators

Operation	Symbol	Description	Example
Equal to	==	Returns true if both values are equal.	value1 == value2
Not equal to	!=	Returns true if values are not equal.	value1 != value2

Example Code

public class BooleanExamples {
    public static void main(String[] args) {
        // Initialize boolean variables
        boolean isJavaFun = true;
        boolean isFishTasty = false;

        // Print boolean values
        System.out.println("Is Java fun? " + isJavaFun);
        System.out.println("Is fish tasty? " + isFishTasty);

        // Logical AND
        boolean resultAnd = isJavaFun && isFishTasty;
        System.out.println("Logical AND: " + resultAnd);

        // Logical OR
        boolean resultOr = isJavaFun || isFishTasty;
        System.out.println("Logical OR: " + resultOr);

        // Logical NOT
        System.out.println("Logical NOT (isJavaFun): " + !isJavaFun);

        // Relational Operations
        System.out.println("Is isJavaFun equal to isFishTasty? " + (isJavaFun == isFishTasty));
        System.out.println("Is isJavaFun not equal to isFishTasty? " + (isJavaFun != isFishTasty));
    }
}
