Hi,
I'm new to Junit and usimg it on JBuilder and was writing simple test case just to see it working; now the following code worked for String but is giving me grief on the line super(testMethodNumber); can anyone see why?

here's all the code;


import junit.framework.TestCase;


class Number {


int number1;


int number2;


int result;


public Number(int n1, int n2) {


number1 = n1;


number2 = n2;


}


public Number() {


number1 = 0;


number2 = 0;


}


public int getNumber() {


result = number1 + number2;


return result;


}
}



class TestNumber extends TestCase {


public TestNumber(int testMethodNumber) {


super(testMethodNumber);


}


// A unit test to verify the number is added correctly


public void test_add_Number() {


Number p = new Number(1,1);


assertEquals(2, p.getNumber());


}



}
