What is the Thread.countStackFrames() function in Java?

The countStackFrames() method is deprecated in the new versions of Java. The definition of this function is dependent upon the suspend() method which is deprecated. Therefore, this method can never be defined properly.

The Thread.countStackFrames() method helps to count the number of stack frames in a thread.

Syntax

Thread.countStackFrames()

Parameters

It does not take any argument value.

Return value

It returns the stack frames count of the thread.

Code example

Here is an example regarding Thread.countStackFrames(). It helps to count the number of stack frames in the current thread.

public class Edpresso {

    // method to return stack frame count

    public static int count_st() 

    {

        return Thread.currentThread().countStackFrames();

    }

    

    public static void main(String args[])

    {

    	Edpresso object = new Edpresso();

        System.out.println("main method called");

        System.out.println(object.count_st());

    }

}

As this function is from a deprecated API, it cannot be run on the latest version of Java.
