BigInteger Problem
I need help with a class project. I am writing a GUI to add, subtract, and multiply 2 Big Integers entered as Strings. This is my code so far. I can not get it to work with my GUI. I am using NetBeans. Thanks for your help.import java.math.BigInteger;
publicclass Integer{
private BigInteger IntegerOne;
private BigInteger IntegerTwo;
//
public Integer(){this(BigInteger.ZERO, BigInteger.ZERO);}
public Integer(BigInteger IntegerOne, BigInteger IntegerTwo){
this.IntegerOne= IntegerOne;
this.IntegerTwo= IntegerTwo;
}
//
public BigInteger manipulate(){return IntegerOne.add(IntegerTwo);}
public BigInteger subtract(){return IntegerOne.subtract(IntegerTwo);}
public BigInteger multiply(){return IntegerOne.multiply(IntegerTwo);}
}
