i have a method that solves the sum between two numbers but if the first number is greater than the second it wont display anything but if i add an if statement i get an error for the method saying unreachable code
 
public int sum(int sum1,int sum2)
{

int sum0;
sum0=(sum1+sum2)*(sum1-sum2+1)/2;

return sum0;


}

try this.
 
public static int sum(int sum1,int sum2)
	{
 
	int sum  = sum1 > sum2 ? (sum1+sum2)*(sum1-sum2+1)/2 : (sum1+sum2)*(sum2-sum1+1)/2;
	
	return sum;
 

	}

no prob buddy :-) is this what you exactly needed or you have done something else...
It's not in this method. Please check up, using the debugger. Catch all exceptions in this thread and see what happens; it should give you exact location.
 
And the body of your method should be just one line:
return (sum1 + sum2) * (sum1 - sum2 + 1) / 2;
 
Of course, what you write is not a mistake, but looks weird…
