Java for Testers – String non-primitive data type

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

In the previous article, I have explained about boolean data type in Java.

In this article, I am going to explain and practically demonstrate String non-primitive data in Java.

Java for Testers – String non-primitive data type

The sequence of characters can be stored into a variable which is declared as String.

For example:

String e = "This is a sample text";

In the above example, we have declared the variable e with the String data type, and hence we are able to store the string values like “QAFox – Software Testing Tutorials” into the variable.

Follow the below steps for practically implementing String 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 String data type and assign the variable with the string value “QAFox – Software Testing Tutorials” as shown below:

Note: The sequence of characters should be enclosed with double quotes to store into the String declared variable as shown below:

Using Data Types Java - String

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

Using Data Types Java - print String

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

Observe that the Program got executed and the String value stored in the variable e got printed as shown below:

Using Data Types Java - printed String

Copy the above-explained code from the below section:

public class Demo {

	public static void main(String[] args) {
		String e = "QAFox - Software Testing Tutorials";


I will explain more about Strings in the upcoming articles.

Here concludes this article.

In the next article, I will explain and demonstrate the byte data type in Java.
