Custom Label #inSalesforce

This is for creating multilingual applications by displaying information like help text or error messages in a user’s native language.

This are custom text values that can be accessed from Apex classes, Visualforce pages, Lightning pages, or Lightning components.

Steps:

Setup | start typing enter Custom Labels | then select Custom Labels.
Create a label | click New Custom Label | To edit a label | click Edit next to the custom label.
Description field - Better to enter an easily recognizable term to identify this custom label. This description is used in merge fields.
To mark the custom label as protected, select Protected Component.
For Categories, enter some text to categorize the label. This field can be used in filter criteria when creating custom label list views. Separate each category with a comma. The total number of characters allowed in the Categories text box is 255.
In the Value text box, enter text up to 1,000 characters. This value can be translated into any language that Salesforce supports.
Save the label.

In your Apex class, reference the label with the syntax System.Label.MyLabelName
