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;

Solution 1

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:

Java

return (sum1 + sum2) * (sum1 - sum2 + 1) / 2;

Of course, what you write is not a mistake, but looks weird…

Solution 2

try this.

Java

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;


	}
