BigInteger Problem

[gemacjr1201]

I am creating a GUI for class and need help with my program. My program takes 2 big integers and adds them together. First how do I declare my 2 Big Integers and then add them together? I have read the API docs , but still need help. Thanks!

import java.math.BigInteger;
public class Integer  {
    private BigInteger IntegerONE; // both entered as strings from GUI
    private BigInteger IntegerTWO;
 
 
    public Integer() {
 
    }
 
 
    public Integer( BigInteger IntegerONE, BigInteger IntegerTWO){
        this.IntegerONE = IntegerONE;   // I am not sure here?
        this.IntegerTWO = IntegerTWO;
    }
    public BigInteger getIntegerONE(){
        return IntegerONE;
    }
    public BigInteger getIntegerTWO(){
        return IntegerTWO;
    }
 
 public BigInteger add(BigInteger val){
 
      return(val);       // Psuedocode says(this + val)
    }

The design for that class is incorrect: your class isn't an Integer (there already is
a core class named Integer so your class' name is confusing). Your class is a
Two Integer Manipulator (let's call it TIM). All it can do is add two BigIntegers;
BigIntegers know how to add another BigInteger to themselves so you hardly
need any code:

public class TIM {
   private BigInteger i1;
   private BigInteger i2;
   //
   public TIM() { this(BigInteger.ZERO, BigInteger.ZERO); }
   public TIM(BigInteger i1, BigInteger i2) {
      this.i1= i1;
      this.i2= i2;
   }
   //
   public BigInteger manipulate() { return i1.add(i2); }
}
 

That is all there is to it.

kind regards,

Thanks you so much!!
