In java how do you check to see if a function returns and exact negative value?

Can't believe I don't know the answer to this, but getting late and SO is my only hope of getting some decent sleep ;)

So far I know these are not it: assert solver.solveArray(array3) == -1 assert solver.solveArray(array3) == (-1)

From stackoverflow

• assertEquals("message", expectedNegativeValue, func() ); ??

  Chris Conway : Oh, are we using JUnit?

• In what way do you know those aren't it? This short but complete program works fine:

  public class Solver
  {
      public static void main(String[] args)
      {
          Solver solver = new Solver();
          assert solver.solveArray(-1) == -1; // Pass
          assert solver.solveArray(-1) == 2;  // Fail
      }
  
      int solveArray(int x)
      {
          return x;
      }
  }
  

• Hard to say based on what you've written, but you may need parentheses

  assert( solver.solveArray(array3) == -1 )
  

• My algorithm was fubar.... thanks for the help anyways
