In the previous article, I have explained about String non-primitive data type.
In this article, I am going to explain and practically demonstrate byte data type in Java.
Java for Testers – byte data type
byte data type also stores the integer values similar to int data type.
But the size of byte data type is 4 times smaller than the int data type.
i.e. int data type is 32 bit and can store the values in the range of -2147483648 to 2147483647
Whereas byte is 8 bit and can store the values in the range of -128 to 127.
In general, we use int data type for storing the integer values into a variable, unless we get any problem where we have to save memory and go with byte data type.
Example of using byte data type:
byte f = 9;
In the above example, we have declared the variable f with the byte data type, and hence we are able to store the integer values in the range of -128 to 127 into the variable.
Follow the below steps for practically implementing byte 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
2) Inside the main() method, let’s create a variable, declare the variable with byte data type and assign the variable with an integer value in the range of -128 to 127 say 9 as shown below:
3) Now print the value stored in the variable by printing the variable using the print statement as shown below:
4) Save the Project and click on the ‘Run’ button.
Observe that the Program got executed and the integer value stored in the byte declared variable f got printed as shown below:
Copy the above-explained code from the below section:
public class Demo {
public static void main(String[] args) {
byte f = 9;
System.out.println(f);
}
}
Here concludes this article.
In the next article, I will explain and demonstrate the short data type in Java.
