Sample Java prg using SQLite ..

Roman number conversion from numeric to roman. The code seems  bigger but it is simple logic, if you want to try copy paste the code in the appropriate class name and execute the main class..... /**  *  */ package numbers; /**  * @author PraveenKumar  *  */ public class RomanConversionImpl implements IromanConversion{ public String convertRomanNumbers(int number) throws Exception { String romanNumber=""; boolean falg=new ISValidNumber().isValidNumber(number); if(!falg){ romanNumber=romanNumber+NumberRangeConversion.converNumber(number); }else{ throw new Exception("Invalid Number please validate your input!!!"); } NumberRangeConversion.reset(); return romanNumber; } } /**  *   */ package numbers; /**  * @author PraveenKumar  *   */ public class NumberRangeConversion { static String roman = ""; public static String conve...

This is basic test case created using JUNIT. Which will give you basic understanding of Junit testcase . /**  *  */ package test; /**  * @author PraveenKumar  *  */ public class JunitTest { public boolean validatePositivenonZero(int a, int b){ if(a > 0 && b > 0){ return false; } return true; } public int add(int a , int b){ return a+b; } public int multiply(int a, int b){ return a*b ; } public double add(double a, double b){ return a+b; } } /**  *   */ package com.junit.testcase.test; import static org.junit.Assert.*; import junit.framework.Assert; import org.junit.After; import org.junit.AfterClass; import org.junit.Before; import org.junit.Test; import test.JunitTest; /**  * @author PraveenKumar  *  */ public class UnitTestCase { private int a; private int b; /** * @throws java.lang.Exception ...

How to implement the hashmap without using HashMap class from java collection util package. This is one of the interview question asked from JP Morgan I haven't answer in the following way but i have tried to explain in Datastructure. It would help someone like me .. :) enjoy this can be enhance in more but to make it simple .. import java.util.ArrayList; import java.util.Arrays; import java.util.List; /**  *  */ /**  * @author PraveenKumar  *  */ public class HashMapDS {  /**   * @param args   */  public static void main(String[] args) {     HashMap map=new HashMap();   for(int i=0;i    map.put("a"+i, i+10);   }   System.out.println(""+map.get("a1")+25);   map.display(map);  } } import java.util.ArrayList; import java.util.List; /**  *  */ /**  * @author PraveenKumar  *  */ public class HashMap { ...
