I have two input column below, in user table external column holds True/False only.
So based on that True and False value we need to swap first name and last name.
Ex- If True then name will not swap else swap.

Java

user.external=(row4.external==null)?null:row4.external;
user.name=(row4.name==null)?null:row4.name;

Source Table:

              Name             external
--------------------------+---------------------
Vinod, Pratap (Corporate) |    False
   Anil Kumar (pilot.net) |     True
          Sukant, Mohanty |     True

When the external column is "True" then output will be below in target table and where is "False" in external column then the name will be swap.
Also the code will skip (Corporate),(pilot.net) as well.

Target Table(Output):

FirstName   Last Name
----------+-----------
     Anil |Kumar 
   Sukant |Mohanty
   Pratap |Vinod

What I have tried:

Java

String str =(row4.external.toString()==True)?True:row4.external.toString();
if(str = True {
String[] strArray = str.split(",");

You cannot compare a string to a boolean value or assign a boolean to a string:

Java

String str =(row4.external.toString() == "True") ? "True" : row4.external.toString();
if(str == "True" {
    String[] strArray = str.split(",");
}

although a less complex way would be:

Java

String[] strArray;
if (row4.external.toString() == "True")
{
    strArray = str.split(",");
}
else {
    strArray = new String[1];
    strArray[0] = row4.external.toString();
}
