Using Custom Labels in a controller

Question

have the below statements using some hard coded strings and I want to make them use as custom labels. So how can I make these statements to use the Custom Labels I created ? custom label:- value A,B,C

else if((caseList[i].gp == 'A' || caseList[i].gp == 'B' || caseList[i].gp == 'C') && (caseList[i+1].gp == 'A' || caseList[i+1].gp == 'B' || caseList[i+1].gp == 'C'))

Answer 1

You can use them like

System.Label.A, System.Label.B, System.Label.C

More details you can check here Custom label in Apex.

First create three separate labels. then do something like

else if((caseList[i].gp == System.Label.A || caseList[i].gp == System.Label.B || caseList[i].gp == System.Label.C) && (caseList[i+1].gp == System.Label.A || caseList[i+1].gp == System.Label.B || caseList[i+1].gp == System.Label.C))

Answer 2

Create a custom Label. Value =A name="Avalue" Value =B name="Bvalue" Value =C name="Cvalue"

Eg;

else if((caseList[i].gp == Label.Avalue || caseList[i].gp == Label.Bvalue ||    caseList[i].gp == Label.Cvalue) && (caseList[i+1].gp ==Label.Avalue || caseList[i+1].gp == Label.Bvalue || caseList[i+1].gp == Label.Cvalue))
