source-code:

public class A {

public A() {}

private static void printStackTrace() {

        StackTraceElement[] stackElements = new Throwable().getStackTrace();

        if(stackElements != null)

        {

            for(int i = 0; i < stackElements.length; i++)

            {

                

System.out.println(""+ stackElements[i]); 

            }

        }

    }

 

    public void methodA() { methodB(); }

    public void methodB() { printStackTrace();}    

    

    public static void main(String[] argv) {

      A a = new A();

      a.methodA();

    }

  }

 

output:

A.printStackTrace(A.java:5)

A.methodB(A.java:16)

A.methodA(A.java:15)

A.main(A.java:20)

 

Note:

StackTraceElement.java

    public String 

toString() {

        return getClassName() + "." + methodName +

            (isNativeMethod() ? "(Native Method)" :

             (fileName != null && lineNumber >= 0 ?

              "(" + fileName + ":" + lineNumber + ")" :

              (fileName != null ?  "("+fileName+")" : "(Unknown Source)")));

    }

另外下面这些方法也可以:

new Exception("hello").printStackTrace();

Thread.getStackTrace()/Thread.getAllStackTraces() since jdk 1.5

Thread.currentThread().dumpStack()
