Inserting ' before and after value in a list
Hi, as a part of Trailhead challenge, I want to insert a ' before and after value in list. My line of code is :
List1.add(''' +'Test'+ i +''' );
This is throwing error message that : expecting a right parentheses, found ' +'. Could you please suggest what could be done.
Line of code : List1.add( 'Test'+ i ); is working fine.
List1.add(''' +'Test'+ i +''' );
This is throwing error message that : expecting a right parentheses, found ' +'. Could you please suggest what could be done.
Line of code : List1.add( 'Test'+ i ); is working fine.
it should be like this,
list1.add('\' Test' +i + '\'');// \' (use escape sequence) to print the '.
Thanks

It worked but Trailhead still shows that challenge is not completed.
Here is my full code :
public class StringArrayTest {
public static List <String> generateStringArray (Integer n) {
List<String> List1 = new List<String> ();
for(Integer i=0;i<n;i++) {
List1.add('\'Test'+ i+'\'' );
}
System.debug(List1);
return List1;
}
}
I am getting following error :
" Challenge not yet complete... here's what's wrong:
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings."
