How to get input data in your test program using Hashmap

In my last post,i described about,what are the technology we can use for a good and simple framework development.
Now you want to know about how to import input data in your test program,
So below are the code for same.
Note: you can arrange package structure according your requirement.

package com.companyName;

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;
import java.util.StringTokenizer;
import com.companyName.*;


public class Test {
String mystring []= new String [10000];
Map mMap = new HashMap();
//if you are using testng then use @BeforeSuite(alwaysRun=true) method and change below constructor to a simple java method.
Test()
{


String sPath=null;
String filename="inputfilename";//Tested with .csv file
int linenumber=0;
String[] temp;
StringTokenizer st = null;
try {
sPath = new java.io.File(".").getCanonicalPath();
System.out.println("Path: "+ sPath);

FileInputStream fileSt = new FileInputStream(sPath+"\\"+filename);
DataInputStream in = new DataInputStream(fileSt);

BufferedReader bufRdr = new BufferedReader(new InputStreamReader(in));
String line = "";
System.out.println("Path: "+ sPath+"\\"+filename);
while((line = bufRdr.readLine()) != null)
{

mystring[linenumber]=line;
TestDataObj TestDataObject = new TestDataObj() ;
System.out.println("Path: "+ sPath+"\\"+filename+TestDataObject);
temp=line.split(",");

System.out.println("Values-->"+temp[0]+"--"+temp[1]+"--"+temp[2]);
TestDataObject.setTestcaseID(temp[0]);
TestDataObject.setUserName(temp[1]);
TestDataObject.setPassword(temp[2]);

mMap.put(temp[0], TestDataObject);
//because temp[0] is a testcase id in my input file so i am using key value in hashmap.
linenumber++;

}
in.close();
}
catch(Exception e)
{

}

}

}

for setter and getter

package com.companyName;

public class TestDataObj {
private String sUserName=null;
private String sPassword=null;
private String sTestcaseID=null;
public String getUserName() {
return sUserName;
}
public void setUserName(String userName) {
this.sUserName = userName;
}
public String getPassword() {
return sUserName;
}
public void setPassword(String password) {
this.sPassword = password;
}

public String getTestcaseID() {
return sTestcaseID;
}
public void setTestcaseID(String testcaseid) {
this.sTestcaseID = testcaseid;
}

}
Test program

package com.companyName;

public class TestData {

public static void main(String args[])
{
Test test= new Test();
TestDataObj testobj=(TestDataObj)test.mMap.get("tc1");
System.out.println(testobj.getTestcaseID());
System.out.println(testobj.getUserName());
System.out.println(testobj.getPassword());
}

}

let me know if have any doubts.
