ok neenu malla 3 to 4 Hrs daaka raanu

so let me past the classes here..

and u create project in eclipse say Calculator(if using eclipse) if not rest of the steps are similar for command prompt as well as eclipse

Create packages
com.myproject.calc
com.myproject.calc.dto
com.myproject.calc.interfaces
com.myproject.calc.implementation
com.myproject.calc.exception

create the following classes

[cherlapalli_jailer]

package com.myproject.calc.dto;

import java.math.BigDecimal;

public class CostDTO {

String costID = new String() ;
BigDecimal costAmount ;
public String getCostID() {
return costID;
}
public void setCostID(String costID) {
this.costID = costID;
}
public BigDecimal getCostAmount() {
return costAmount;
}
public void setCostAmount(BigDecimal costAmount) {
this.costAmount = costAmount;
}
}

[cherlapalli_jailer]

package com.myproject.calc.interfaces;

import com.myproject.calc.dto.CostDTO;
import com.myproject.calc.exception.CheckException;


public interface CostCalculatorInterface {

public CostDTO add(CostDTO obj1,CostDTO obj2) throws CheckException;
public CostDTO substract(CostDTO obj1,CostDTO obj2) throws CheckException;

}

[cherlapalli_jailer]

package com.myproject.calc.implementation;

import com.myproject.calc.dto.CostDTO;
import com.myproject.calc.exception.CheckException;
import com.myproject.calc.interfaces.CostCalculatorInterface;

public class CostCalculator implements CostCalculatorInterface{

public CostDTO add(CostDTO obj1 , CostDTO obj2) throws CheckException
{
//MathContext mc = new MathContext(0);
CostDTO retObj = new CostDTO() ;
String id1 = obj1.getCostID() ;
String id2 = obj2.getCostID() ;
if(id1.equalsIgnoreCase(id2))
{
retObj.setCostID(id1);
retObj.setCostAmount(obj1.getCostAmount().add( obj2.getCostAmount()));
}
else
throw new CheckException("Both Objects should carry same ID values to proceed further.");


return retObj ;
}
public CostDTO substract(CostDTO obj1 , CostDTO obj2) throws CheckException
{

CostDTO retObj = new CostDTO() ;
String id1 = obj1.getCostID() ;
String id2 = obj2.getCostID() ;
if(id1.equalsIgnoreCase(id2))
{
retObj.setCostID(id1);
retObj.setCostAmount(obj1.getCostAmount().subtract( obj2.getCostAmount()));

}
else
throw new CheckException("Both Objects should carry same ID values to proceed further.");

return retObj ;
}
}

[cherlapalli_jailer]

package com.myproject.calc.exception;

public class CheckException extends Exception {
public CheckException(String message) {
super(message);
}
}

[cherlapalli_jailer]

package com.myproject.calc;

import java.math.BigDecimal;

import com.myproject.calc.dto.CostDTO;
import com.myproject.calc.exception.CheckException;
import com.myproject.calc.implementation.CostCalculator;
import com.myproject.calc.interfaces.CostCalculatorInterface;

public class TextCalc {

public CostDTO createDTO(String id, BigDecimal cost) {
CostDTO costDTO = new CostDTO();

costDTO.setCostID(id);
costDTO.setCostAmount(cost);
return costDTO;
}

public static void main(String args[]) {
TextCalc tc = new TextCalc();

CostDTO obj1 = tc.createDTO("2", new BigDecimal(123.00));
CostDTO obj2 = tc.createDTO("2", new BigDecimal(103.00));
CostDTO outputObj = new CostDTO();

CostCalculatorInterface cci = new CostCalculator();
try {
outputObj = cci.add(obj1, obj2);
} catch (CheckException ce) {
System.out.println(ce.getMessage());
System.exit(1) ;
}

System.out.println("Input values are \n ID = "+obj1.getCostID()+"\nObj1 Cost: "+obj1.getCostAmount()+"\nObj2 Cost: "+obj2.getCostAmount());
System.out.println("Add\nID | COST\n"+outputObj.getCostID()+" | "+outputObj.getCostAmount());

} catch (CheckException ce) {
System.out.println(ce.getMessage());
System.exit(1) ;
}

System.out.println("Subtract\n"+outputObj.getCostID()+" | "+outputObj.getCostAmount());

}
