package TrackingStack;

import java.io.Serializable;

class SelfException extends RuntimeException {
    SelfException() {}
    SelfException(String msg){super(msg);}
}
public class PtintStackTrace {
    public static void main(String args[]){
        first();
    }

    public static void first(){
        second();
    }

    public static void second(){
        third();
    }

    public static void third(){
        throw new SelfException("Exception~");
    }
}

运行这个程序，可以看到控制台打印出一连串的异常信息，这些信息记录了异常的发生，如下

Exception in thread "main" TrackingStack.SelfException: Exception~
	at TrackingStack.PtintStackTrace.third(PtintStackTrace.java:23)
	at TrackingStack.PtintStackTrace.second(PtintStackTrace.java:19)
	at TrackingStack.PtintStackTrace.first(PtintStackTrace.java:15)
	at TrackingStack.PtintStackTrace.main(PtintStackTrace.java:11)

下面是另外一个例子，异曲同工

package TrackingStack;

public class ThreadException implements Runnable {
    public void run(){
        firstMethod();
    }
    public void firstMethod(){
        secondMethod();
    }
    public void secondMethod(){
        int a = 5;
        int b = 0;
        int c = a / b;
    }
    public static void main(String args[]){
        new Thread(new ThreadException()).start();
    }
}

控制台输出的信息：

Exception in thread "Thread-0" java.lang.ArithmeticException: / by zero
	at TrackingStack.ThreadException.secondMethod(ThreadException.java:13)
	at TrackingStack.ThreadException.firstMethod(ThreadException.java:8)
	at TrackingStack.ThreadException.run(ThreadException.java:5)
	at java.lang.Thread.run(Thread.java:748)

异常捕获就到这里
