Can we create object inside class in Java?

In java you cannot create a method outside of a class. All methods must be encapsulated within a class. Therefore the main method as an entry point to the program must be within a class.

How do you traverse an array of objects in Java?

Iterating over an array You can iterate over an array using for loop or forEach loop. Using the for loop − Instead on printing element by element, you can iterate the index using for loop starting from 0 to length of the array (ArrayName. length) and access elements at each index.

How do you make a loop object dynamic?

To create a dynamic object in a loop with JavaScript, we can use the square bracket notation to add properties to an object dynamically. We create an empty object and assign it to the objects variable. Then we add a for loop that loops through some numbers. And we use the numbers as property names with objects[x] .

Why can’t I access the last object created in Java?

With no reference to the objects, the Garbage Collector comes in and frees that memory, deleting the objects. So, you won’t be able to access not even the last object created. If you modify the code like this, at the end of this code you will have only the last object instantiated:
