The Code I was trying out is as below
public void dump(InputStream in) throws Exception {
File output_file = new File((configData.get("OUTPUT_FILE_DIR") +
TESTCASE_NAME + "#"+configData.get("TEST_NUM")+(".txt")));
System.out.println("TestCase: "+TESTCASE_NAME);
System.out.println("OUTPUT_FILE_DIR: "+configData.get("OUTPUT_FILE_DIR"));
System.out.println(configData.get("OUTPUT_FILE_DIR") + TESTCASE_NAME +
".txt");
output_file.createNewFile();
final PrintStream out = new PrintStream(new FileOutputStream(output_file,
false));
out.println("CLASS ID HITS/PROBES CLASS NAME");
System.out.println("INDATE in"+in);
//String results = new BufferedReader (new
InputStreamReader(in)).lines().collect(Collectors.joining("\n"));
//System.out.println("INDATE"+results);
final ExecutionDataReader reader = new ExecutionDataReader(in);
reader.setSessionInfoVisitor(new ISessionInfoVisitor() {
public void visitSessionInfo(final SessionInfo info) {
out.printf("Session \"%s\": %s - %s%n", info.getId(), new
Date(info.getStartTimeStamp()),
new Date(info.getDumpTimeStamp()));
}
});
reader.setExecutionDataVisitor(new IExecutionDataVisitor() {
public void visitClassExecution(final ExecutionData data) {
CLASS_NAME =
data.getName();//"oracle/apps/scm/productModel/items/ui/bean/ItemOverviewBean";//
long CLASS_ID = data.getId();
Date todayDate = new Date();
final DateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
System.out.println("Today DAte is :" + sdf.format(todayDate));
System.out.println("CLASS_NAME:"+CLASS_NAME);
System.out.println("CLASS_ID:"+CLASS_ID);
//Test method level coverage

// For instrumentation and runtime we need a IRuntime instance

original.close();
// Let's dump some metrics and line coverage information:

}
}
}catch(Exception e){
e.printStackTrace();

}
//}
});
reader.read();
in.close();
System.out.println();
}
/** Currently hardcoded the file details to validate **/
public InputStream getTargetClass() throws Exception{

}
