Looping on String split

Summary:

Hi, I am trying to achieve the following java logic in Oracle Integration Cloud. Basically I am getting comma separated string as input. I want to split the string(Test1,Test2,Test3) based on the comma, iterate it, and in the loop send each split string (ex:test1) to the external REST service as input.

public class MyClass {

  public static void main(String args[]) {

          String vInputIntgs = "Test1,Test2,Test3";

String comma = ","; // To search ',' from the first occurrence of the specified string

int start = 0, end;

end = vInputIntgs.indexOf(comma, start);

System.out.println(end);

while (end != -1) {

String split = vInputIntgs.substring(start, end);
