    I just want to let you know that, there is a problem with the code i.e the use of the static keyword for the head variable in the Stack class makes it a class-level variable, shared across all instances of the class. This means if you create multiple instances of the Stack class, they will share the same head, which can lead to issues when working with multiple independent stacks.
    To have multiple independent stacks, you should make the head variable non-static. Each instance of the Stack class should have its own instance variable for head.And eventually all the methods should be non static to access the head variable.

      @@palakmeena3441 if we make all the methods and the stack class non static, then main will raise an error, since main is static and is trying to access a non static class and its methods. I think the only way to get around this is to implement the stack class in a different .java file within the same package, compile seperately and use them.

    • @prajvalgandhi6258
      @prajvalgandhi6258 5 หลายเดือนก่อน

      No need to make different stack class. Just include function directly in StackClass class similarly like the implementation of LinkedList in previous videos
