Custom Label in Apex Class and Vf Page Salesforce

Hello Friends, today we will learn Custom Label in Apex Class and VF Page(Visualforce Page) Salesforce. We use custom labels for translation text. Custom labels are simple text values that are accessed directly in the Apex class and VF page.

For creating custom labels,
Go To Setup —> Create — > Custom Labels.
Click on New Custom Labels. Enter the value for name, value, and description.
We can use custom label names to access custom label values in apex code using System.Label.labelName

and in Visualforce {!$Label.labelName}
