例子
下面的例子显示java.lang.Thread.dumpStack()方法的使用。
package com.yiibai 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() } }
让我们来编译和运行上面的程序，这将产生以下结果：
Thread = Thread[Admin Thread,1,main] currently active threads = 1 java.lang.Exception: Stack trace at java.lang.Thread.dumpStack(Thread.java:1266) at CheckAccess.main(CheckAccess.java:15)
