Writing Variables using Beanshell Sampler in JMeter into a txt/csv file

My requirement is to write two values using 2 Beanshell Samplers used in different steps, in a single line and separated by a comma But the second variable is written on a new line

I have two different Beanshell Samplers at different steps. First one captures Variable 1 and writes it in a file Second one captures Variable 2 and writes it in the file

First Code:

String path= FileServer.getFileServer().getBaseDir() + "//P_IssuePolicy.txt";
SubmissionNum= vars.get("CP_SubmissionNumber");
EMailID= vars.get("P_emailID");
f = new FileOutputStream(path, true);
p = new PrintStream(f);
this.interpreter.setOut(p); 
p.println(EMailID+","+SubmissionNum);
f.close();

Second Code:

String path= FileServer.getFileServer().getBaseDir() + "//P_IssuePolicy.txt";
Policynumber= vars.get("CP_Policynumber");
f = new FileOutputStream(path, true); 
p = new PrintStream(f);
this.interpreter.setOut(p);
p.println(","+Policynumber);
f.close();

Expected Result:

 [email protected],12345601,12345602

Actual Result:

 [email protected],12345601
