Pointers in Java are variables that store memory addresses of other variables or objects.
Pointers in Java are not directly supported like in languages such as C or C++.
Instead, Java uses references to objects, which act like pointers but with restrictions.
Example: String str = new String("Hello"); // str is a reference to the String object
