java.lang.NullPointerException: Cannot invoke method on nul…

The error indicates that your code attempted to invoke a method on an object reference that has not been initialized, meaning it is null. This often happens when an object is expected to be created but isn't, leading to a runtime exception.

It broke because the code assumes that an object is instantiated before calling a method on it. If the object is null, Java cannot find the method to execute, resulting in a NullPointerException.

To fix this, ensure that the object is properly initialized before invoking any methods on it. You can add a null check before the method call or ensure that the object is instantiated correctly in your code.
