POstopping a stopwatch on its current time

Body
copied!<p>What I'm trying to do is add a stop function on this already existing code. I thought that I could implement a stopping function if I were to put an String input to where if I were to type s for stop, the program would stop on the current time. So when I press s, it does the same as if it were to run without the if statement</p> <pre><code>public class Stopwatch { private final long t; public Stopwatch() { t=System.currentTimeMillis(); } public double elapsedTime() { return (System.currentTimeMillis() - t) / 1000.0; } public double stopping(double newton, double time, double totnewt, double tottime) { double timeNewton = newton; double timeMath = time; double totalNewton = totnewt; double totalMath = tottime; StdOut.println(totalNewton/totalMath); StdOut.println(timeNewton/timeMath); return time; } public static void main(String[] args) { System.out.println("Enter N:"); int N = StdIn.readInt(); double totalMath = 0.0; Stopwatch swMath = new Stopwatch(); for (int i = 0; i < N; i++) totalMath += Math.sqrt(i); double timeMath = swMath.elapsedTime(); double totalNewton = 0.0; Stopwatch swNewton = new Stopwatch(); for (int i = 0; i < N; i++) totalNewton += Newton.sqrt(i); double timeNewton = swNewton.elapsedTime(); String s = StdIn.readString(); if (s == "s") { swMath.stopping(timeNewton, timeMath, totalNewton, totalMath); swNewton.stopping(timeNewton, timeMath, totalNewton, totalMath); } StdOut.println(totalNewton/totalMath); StdOut.println(timeNewton/timeMath); } } </code></pre>
