List of contents of classes in Java

People, is there somewhere on the web where I can find a list of the contents of standard Java classes? Let's say I wanted to know what functions the Math class contains. Can anyone point me in the right direction?

I just feel like a beginner. Sorry for the dumb question :-)

Thanks in advance,

Dave

If you don't have access to the Internet or JavaDoc, the utility javap

is at your disposal. It comes bundled with the JDK.

This is how you use it



C:\>javap java.lang.Math
Compiled from "Math.java"
public final class java.lang.Math {
  public static final double E;
  public static final double PI;
  public static double sin(double);
  public static double cos(double);
  public static double tan(double);
  public static double asin(double);
  public static double acos(double);
  public static double atan(double);
  public static double toRadians(double);
  public static double toDegrees(double);
  public static double exp(double);
  public static double log(double);
  public static double log10(double);
  public static double sqrt(double);
  public static double cbrt(double);
  public static double IEEEremainder(double, double);
  public static double ceil(double);
  public static double floor(double);
  public static double rint(double);
  public static double atan2(double, double);
  public static double pow(double, double);
  public static int round(float);
  public static long round(double);
  public static double random();
  public static int abs(int);
  public static long abs(long);
  public static float abs(float);
  public static double abs(double);
  public static int max(int, int);
  public static long max(long, long);
  public static float max(float, float);
  public static double max(double, double);
  public static int min(int, int);
  public static long min(long, long);
  public static float min(float, float);
  public static double min(double, double);
  public static double ulp(double);
  public static float ulp(float);
  public static double signum(double);
  public static float signum(float);
  public static double sinh(double);
  public static double cosh(double);
  public static double tanh(double);
  public static double hypot(double, double);
  public static double expm1(double);
  public static double log1p(double);
  public static double copySign(double, double);
  public static float copySign(float, float);
  public static int getExponent(float);
  public static int getExponent(double);
  public static double nextAfter(double, double);
  public static float nextAfter(float, double);
  public static double nextUp(double);
  public static float nextUp(float);
  public static double scalb(double, int);
  public static float scalb(float, int);
  static {};
}
