    • Method Detail

      • getStackTrace

        public static java.lang.StackTraceElement[] getStackTrace()
        Retrieves the stack trace elements for the current thread's call stack.

        This method is useful for inspecting the sequence of method calls that led to the current point of execution. It can be used for debugging, logging, or monitoring purposes.

        Example Usage

        
 StackTraceElement[] stackTrace = StackTraceUtils.getStackTrace();
 for (StackTraceElement element : stackTrace) {
     System.out.println(element);
 }
        Returns:
        a non-null array of StackTraceElement representing the current thread's stack trace

      • getCallerClassName

        public static java.lang.String getCallerClassName()
        Retrieves the fully qualified name of the class that called this method.

        This method utilizes either java.lang.StackWalker (available in JDK 9+) or falls back to using StackTraceElement to determine the caller's class name. It ensures compatibility across different JVM versions.

        Example Usage

        
 String callerClassName = StackTraceUtils.getCallerClassName();
 System.out.println("Caller class: " + callerClassName);
        Returns:
        the fully qualified name of the calling class
        Throws:
        java.lang.IndexOutOfBoundsException - if the stack trace does not have enough frames to determine the caller
