Question

伙计们，网上有什么地方可以找到标准Java类的内容列表吗？说我想知道Math类包含哪些函数。有人可以指出我正确的方向吗？

作为一名初学者，只是感觉我的方式。抱歉这个愚蠢的问题： - ）

提前致谢，

Answer 1

Oracle Java API

Answer 2

如果您无法访问Internet或JavaDoc，则可以使用javap实用程序。它与JDK捆绑在一起。

这就是你使用它的方式

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 {};
}
