mytimer.java

基于java的3d开发库。对坐java3d的朋友有很大的帮助。

public class MyTimer
{
    private String my_name;
    private long start_time;
    private long stop_time;
    private boolean running = false;
    private double elapsed_seconds;
    
    MyTimer(String string) {
        my_name = string;
        elapsed_seconds = 0.0;
        System.out.println("Timer [" + my_name + "] started");
        start();
    }
    
    public double elapsed() {
        if (running) {
            long l = System.currentTimeMillis();
            elapsed_seconds = (double) (l - start_time) / 1000.0;
        }
        return elapsed_seconds;
    }
    
    public void start() {
        start_time = System.currentTimeMillis();
        running = true;
    }
    
    public void stop() {
        stop_time = System.currentTimeMillis();
        running = false;
        elapsed_seconds = (double) (stop_time - start_time) / 1000.0;
        System.out
            .println("Timer [" + my_name + "] stopped at " + elapsed_seconds);
    }
    
    public String toString() {
        return Double.toString(elapsed_seconds);
    }
}
