使用方法java.lang.Class.getMethods()提供了由对象表示的类或接口的所有公共方法的列表。公共方法包括由类或接口声明的方法，以及由类或接口继承的方法。
另外，getMethods()如果类或接口没有公共方法，或者在Class对象中表示原始类型，数组类或void ，则该方法返回零长度数组。
演示此的程序如下所示-
import java.lang.reflect.Method;
public class Main {
public static void main(String[] argv) throws Exception {
Class c = java.lang.Thread.class;
Method[] methods = c.getMethods();
System.out.println("The public methods of the java.lang.Thread class are:\n");
for (int i = 0; i < methods.length; i++) {
System.out.println(methods[i]);
}
}
}输出结果
The public methods of the java.lang.Thread class are: public void java.lang.Thread.run() public java.lang.String java.lang.Thread.toString() public boolean java.lang.Thread.isInterrupted() public static native java.lang.Thread java.lang.Thread.currentThread() public final java.lang.String java.lang.Thread.getName() public synchronized void java.lang.Thread.start() public final synchronized void java.lang.Thread.join(long,int) throws java.lang.InterruptedException public final synchronized void java.lang.Thread.join(long) throws java.lang.InterruptedException public final void java.lang.Thread.join() throws java.lang.InterruptedException public final java.lang.ThreadGroup java.lang.Thread.getThreadGroup() public java.lang.StackTraceElement[] java.lang.Thread.getStackTrace() public static native boolean java.lang.Thread.holdsLock(java.lang.Object) public final void java.lang.Thread.checkAccess() public static void java.lang.Thread.dumpStack() public static native void java.lang.Thread.yield() public final void java.lang.Thread.setPriority(int) public final void java.lang.Thread.setDaemon(boolean) public static native void java.lang.Thread.sleep(long) throws java.lang.InterruptedException public static void java.lang.Thread.sleep(long,int) throws java.lang.InterruptedException public final synchronized void java.lang.Thread.stop(java.lang.Throwable) public final void java.lang.Thread.stop() public void java.lang.Thread.interrupt() public static boolean java.lang.Thread.interrupted() public void java.lang.Thread.destroy() public final native boolean java.lang.Thread.isAlive() public final void java.lang.Thread.suspend() public final void java.lang.Thread.resume() public final int java.lang.Thread.getPriority() public final synchronized void java.lang.Thread.setName(java.lang.String) public static int java.lang.Thread.activeCount() public static int java.lang.Thread.enumerate(java.lang.Thread[]) public native int java.lang.Thread.countStackFrames() public final boolean java.lang.Thread.isDaemon() public java.lang.ClassLoader java.lang.Thread.getContextClassLoader() public void java.lang.Thread.setContextClassLoader(java.lang.ClassLoader) public static java.util.Map java.lang.Thread.getAllStackTraces() public long java.lang.Thread.getId() public java.lang.Thread$State java.lang.Thread.getState() public static void java.lang.Thread.setDefaultUncaughtExceptionHandler(java.lang.Thread$UncaughtExceptionHandler) public static java.lang.Thread$UncaughtExceptionHandler java.lang.Thread.getDefaultUncaughtExceptionHandler() public java.lang.Thread$UncaughtExceptionHandler java.lang.Thread.getUncaughtExceptionHandler() public void java.lang.Thread.setUncaughtExceptionHandler(java.lang.Thread$UncaughtExceptionHandler) public final void java.lang.Object.wait(long,int) throws java.lang.InterruptedException public final native void java.lang.Object.wait(long) throws java.lang.InterruptedException public final void java.lang.Object.wait() throws java.lang.InterruptedException public boolean java.lang.Object.equals(java.lang.Object) public native int java.lang.Object.hashCode() public final native java.lang.Class java.lang.Object.getClass() public final native void java.lang.Object.notify() public final native void java.lang.Object.notifyAll()
