Question

Hi there, so I'm writting a java program that adds and subtracts two really big numbers that are being stored in ArrayList. Therefore, I have a boolean method called getBigger() that returns true if the fisrt number in the argument of parameters is bigger that the second:

example:

public boolean getBigger(ArrayList<Integer> number1, ArrayList<Integer> number2){

// it returns true if "number1" is bigger than "numer2"

I could do this by checking its size, howeve lets say that:

the number beign passed in number1 is: 22444444555663

the number being passed in number2 is: 22111111111223

how could I check for the biggest one if the size is the same?

Please help!

Explanation / Answer

public boolean getBigger(ArrayList<Integer> number1, ArrayList<Integer> number2)

{

if(number1.size() > number2.size())

return true;

else if(number1.size() < number2.size())

return false;

else

{

int a,b,temp;

Iterator itr1 = number1.iterator();

Iterator itr2 = number2.iterator();

while(itr1.hasNext())

{

a = (itr1.next()).intValue();

b = (itr2.next()).intValue();

if(a>b)

return true;

else if(b>a)

return false;

}

}

}
