例子 (Example)

以下示例显示了java.lang.Thread.dumpStack（）方法的用法。

package com.iowiki;
import java.lang.*;
public class ThreadDemo {
   public static void main(String[] args) {
      Thread t = Thread.currentThread();
      t.setName("Admin Thread");
      // set thread priority to 1
      t.setPriority(1);
      // prints the current thread
      System.out.println("Thread = " + t);
      int count = Thread.activeCount();
      System.out.println("currently active threads = " + count);
      /* prints a stack trace of the current thread to the standard
         error stream, used for debugging */
      Thread.dumpStack();
   }
}

让我们编译并运行上面的程序，这将产生以下结果 -

Thread = Thread[Admin Thread,1,main]
currently active threads = 1
java.lang.Exception: Stack trace
