A Boolean expression returns a boolean value: true or false. This is useful to build logic, and find answers. For example, you can use a comparison operator , such as the greater than ( > ) operator, to find out if an expression (or a variable) is true or false:

The boolean keyword in Java is a primitive data type that can hold only two possible values: true or false. It is used to represent simple flags that track true/false conditions, and it is the basis for all conditional operations in Java.

Apr 1, 2025 · Learn what is a Boolean in Java, how to declare & return a Java Boolean, and what are boolean operators along with practical code examples: In this tutorial, we are going to explore boolean in Java which is a primitive data type. This data type has two values i.e. “true” or “false”.

Sep 1, 2021 · Java Boolean is an inbuilt class that wraps are used for wrapping the value of primitive data type, i.e. boolean in an object. The boolean class contains two values, i.e. true or false. Java provides a wrapper class Boolean in java.lang package.

In this short article, we will discuss everything about the boolean keyword in Java. Defines a boolean variable for the values "true" or "false" only. By default, the value of boolean primitive type is false. This keyword is also used to declare that a method returns a value of the primitive type boolean. boolean is a Java primitive type.

Jan 9, 2025 · Here’s a simple example of declaring a Boolean variable in Java: This statement creates a Boolean variable named isJavaFun and initializes it with the value true. The two values that a Boolean can take— true and false —represent the two possible states of logical expressions. Understanding how these values function is critical for any developer.

Dec 19, 2024 · Booleans are often used in if-else statements to determine which block of code should execute. Example: public static void main(String[] args) { boolean isEligible = true; if (isEligible) { System.out.println("You are eligible."); } else …

This tutorial covers various aspects of the Java boolean data type, including: The type of values a boolean can store. How to declare, initialize, and update a boolean variable. Default value of a static boolean variable. Printing a boolean value to the console output. Using boolean in conditional statements and control flow.

Let us see the boolean expression in a java program. public static void main(String args[]) int x=9; int y=12; System.out.println("x = "+x); System.out.println("y = "+y); System.out.println("Is x > y? Answer:"+(x>y)); //Here the x>y is a Boolean expression. System.out.println("Is x = y? Answer:"+(x==y)); //Here the x==y is a Boolean expression.

Nov 11, 2012 · With this example we are going to demonstrate how to use a boolean type in Java. The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions.
