Hi well I creating a program with two classes and one of those classes is a test class which test the other class that basically is an ADT of giant number of 100 digits. but I'm having a problem and I do not know what is it here is my code:
public class GiantNumber
{
private short[] digitsArray;
public GiantNumber(int value)
{
this();
int x = 99;
while (value !=0);
{
digitsArray[x] = (short) (value % 10);
value = value /10;
x--;
}
}
public GiantNumber ()
{
for (int j = 0; j < 100; j++)
{
digitsArray [j] = 0;
}
}
public void add(GiantNumber otherNumber)
{
int a = 0;
int b = 0;
for(int y = 99; y >= 0; y--)
{
this.digitsArray[y] += otherNumber.digitsArray[y] + a;
this.digitsArray[y] = (short) b;
b = this.digitsArray[y] % 10;
a = this.digitsArray[y] / 10;
}
}
public void substract(GiantNumber otherNumber1)
{
GiantNumber a = new GiantNumber(20);
GiantNumber b = new GiantNumber(15);
a.substract(b);
}
public void greater()
{
}
public boolean equals()
{
return true;
}
public String toString();
{
}
}
public class TestGiantNumber
{
public static void main(String[] args)
{
TestGiantNumber GiantNumber = new TestGiantNumber();
GiantNumber a = new GiantNumber(2);
GiantNumber b = new GiantNumber(2);
a.add(b);
}
public TestGiantNumber()
{
}
}
and when I run the program the error is:

I see that you have two public classes in your program.
public class GiantNumber
and
public class TestGiantNumber
Only one class per java source file can be "public"


Thanks, leo

Jose,
After 21 posts you still didn't use code tags and you used the subject line of "URGENT" (in all upper case letters).

Do you know how many people will avoid your post because of these two things?
