Java for Testers – boolean data type

<<Previous Post                    << Complete Tutorial>>                        Next Post>>

In the previous article, I have explained about char data type.

In this article, I am going to explain and practically demonstrate boolean data type in Java.

Java for Testers – boolean data type

Only true or false values can be stored into a variable which is declared with the boolean data type.

For example:

boolean d = true;

In the above example, we have declared the variable d with the boolean data type, and hence we are able to store the boolean values like true into the variable.

Follow the below steps for practically implementing boolean data type in Java:

1) Let’s create a Java program and create a Demo class as shown below:

Note: If you are not aware of creating a Java project and a Class in Java, refer to our previous article – Creating a Java project in Eclipse IDE

Print statements - Java project

2) Inside the main() method, let’s create a variable, declare the variable with boolean data type and assign the variable with the boolean value true as shown below:

Using Data Types Java - boolean

3) Now print the value stored in the variable by printing the variable using the print statement as shown below:

Using Data Types Java - boolean printed

4) Save the Project and click on the ‘Run’ button.

Observe that the Program got executed and the boolean value true stored in the variable d got printed as shown below:

Using Data Types Java - printed boolean

Copy the above-explained code from the below section:

public class Demo {

	public static void main(String[] args) {
		boolean d = true;


Here concludes this article.

In the next article, I will explain and demonstrate the String Non-Primitive data type in Java.
