Initializing objects in Java without declaring a class or using a class

I have general question regarding objects in Java. I want to initialize an object in Java without declaring a class or using a class.

In python for example you can do like this:

myObject = {"x":5,"y":10,"z":12,"name":"something"}


Now myObject is an object. And I can say myObject.x which will be 5.

From what I know I would have to do like this in Java:

class object(){
int x;
int y;
int z;
String name;
myObject(int x, int y, int z, String name){
this.x = x;
this.y = y;
this.z = z;
this.name = name;
}
}

myObject = new object(10,5,12,"something")


I would like to do that, but like in my python example.
Hope anyone can help :)

myObject.get('x')

Java is statically typed so you can't point a variable to an instantiated object without declaring the class.

You can create classes without a pointer but they will just be collected by the garbage collection machine unless you're passing them to something that uses the new object you're creating.

This is nothing in Java:

myObject = {"x":5,"y":10,"z":12,"name":"something"}

Java doesn't know what to do with it.

Java is not python, and you cannot instantiate a Java object with an anonymous Dict (the only type of object you can instantiate with a syntax like that is an array). That is, this

Dict

int a = {1, 2, 3};


is legal in Java.
