Example

public class JavaGetStackTraceExp 
{
    public static void main(String args[]) 
    {
    first();
    } 
    public static void first()
    {
        second();
    }
    public static void second() 
    {
        third();
    }
    public static void third() 
    {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        System.out.println("Displaying Stack trace using StackTraceElement in Java");
        for(StackTraceElement st : stackTrace)
        {
            // print the stack trace 
            System.out.println(st);
        }
    }
}
