Selenium – For loop to navigate to the web element list and verify list item.

Step 1: Store item of the list in a List using findElements

List<WebElement> searchResultlist = Driver.driver.findElements(By.xpath("//span[@class='document-name']"));

Step 2: Use for loop to traverse in the list and verify the text using IF condition.
To make sure input by the user and text from the application are in same case, convert both the strings in UPPER case and match.

for (WebElement resultList : searchResultlist){
     System.out.println(resultList.getText());
     if (resultList.getText().toUpperCase().contains(DocumentNumber.toUpperCase())){
         resultList.click();
         break;
    }
}

Run below command to install JAVA 

yum install java-1.8*

Once the installation is completed, run below command to check JAVA Version.

java -version

Above command should give you the following result.

openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

Run below command to find the JAVA path.

find /usr/lib/jvm/java-1.8* | head -n 3

Above command should give you the following results.

/usr/lib/jvm/java-1.8.0
/usr/lib/jvm/java-1.8.0-openjdk
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64

Use last path from above result to update the bash profile.

To update the bash profile run below command.

vi .bash_profile

Update bash_profile as below.

JAVA_HOME = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64
PATH=$PATH:$JAVA_HOME:$HOME/.local/bin:$HOME/bin

Save and Exit the bash_profile.

Refresh the bash profile using the below command.

source ~/.bash_profile

After refresh, run the following command to verify the JAVA path.

echo $JAVA_HOME

Output of the above command should be:

/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64
