Thread类的dumpStack()方法将当前线程的堆栈跟踪打印到标准错误流。它仅用于调试。
语法
public static void dumpStack()
返回
此方法不返回任何值。
示例
public class JavaDumpStackExp
{
public static void main(String[] args)
{
Thread thread = Thread.currentThread();
thread.setName("My ThreadDumpStack");
// set thread priority to 6
thread.setPriority(6);
// prints the current thread
System.out.println("Current thread: " + thread);
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();
}
}
执行上面示例代码，得到以下结果：
Current thread: Thread[My ThreadDumpStack,6,main]
currently active threads: 1
java.lang.Exception: Stack trace
