Write the below code to get Correlated values to CSV file.We have two Options while values sending to csv file:
1. Overwriting File for each Correlated value for each user
2. Appending Value for each time

1.Overwriting File for each Correlated value for each user:
SID_J=vars.get("SID");

f = new FileOutputStream("C:\\OfficeWork\\Java\\id.txt"); //Windows

p = new PrintStream(f);
this.interpreter.setOut(p);
print(SID_J);
f.close();

2.Appending Value for each time :
SID_J=vars.get("SID");
// Pass true if you want to append to existing file
// If you want to overwrite, then don't pass the second argument
f = new FileOutputStream("C:\\OfficeWork\\Java\\id.txt",true); //Windows
p = new PrintStream(f);
this.interpreter.setOut(p);
print(SID_J);
f.close();
