Step 1: Go to the Java verification page by clicking here. Step 3: After choosing Run , the page will show the current Java version and the available latest Java version. If you want to install the new version, click on it to download it. If your drivers get outdated, you may encounter some errors that can affect the computer use.

How to check if drivers are up to date? Steps are here. For that, you can refer to the following steps. Step 5: Navigate to the General tab and then click the About button. As for games, Minecraft Windows 10 or Java edition, which one is better?

All Java versions have 1 in the beginning followed by the number of major JRE version it is 8 in my case and the update number. You can display the current Java version in the command prompt. Run cmd. You can check Java version installed on your computer using PowerShell. You can just check the version of the executable file java. Display the java file version:. If you want to get Java versions used on all computers or servers in your domain, you can use the following PowerShell script.

The script can get the information from all servers remotely according to the list you enter manually or from a text file. You can use the following PowerShell script to remove all installed Java versions on a local computer:. Instead, you can get a list of installed Java versions from the registry and uninstall all of them by their product GUID generated when you install software via MSI.

To understand how to create test cases, let's create a simple class and examine it. Let's create a class DemoClass in Eclipse where we have performed a simple addition method by following the below steps:. Under Wizards , you will see the Maven repository, click on the dropdown, click on Maven Project , and then click on Next.

A snapshot is shown below:. Here, we have done a simple project, so we have selected the 'Create a simple project' option and then click on Next, as you can see in the below snapshot:. Group Id: It is the unique name that helps in identifying one project group from other.

It follows the Java naming rule convention, and so it must be provided as com. Artifact Id: It is the unique name that is given to the project we are going to create. So, for our project, we have provided the following Group Id and Artifact Id i.

Here, we have created java , where we have implemented a simple method of adding two numbers. The code is as follows:. Then click on Finish. The JUnit test case will be created. Here, we have used the New Junit 4 test. To test a class or method, we need to use the testing annotations, and here we have Test annotation before the test method. Test Case 1: We have created a test case where we have tested whether on providing two values, we get the respective sum or not.

If not, the test case will be failed, but for the above values, we got the following output:. Hence, our test case passed successfully, which is indicated by the green symbol. Test Case 2: If we pass the same code for the calculated parameters 10, 15 but the expected value as and have the following values to test, we get our test case failed. The code is as:. So, we got our test case failed, which means our code is correct, and it is indicated by the Red signal, as you can see in the below snippet:.

Test Case 3: If we pass a negative and a positive value for the calculated parameters as -5, 8 , and expected parameter value as 3 , we get our test case passed successfully, as you can see in the below snippet:. However, if we pass 5, -8 as calculated value and expected value as 3, the test case would fail definitely.
