Instances Of Objects In Java Versus Other Languages

I am learning JAVA and understanding some of its specific oddities. For example I notice that JAVA loves instances but not variables.

In Python:
x = 1
y = 2
print(x,y)
yields (1,2)

then I do y = x and print
getting (1,1)

This makes sense to me since x and y are variables and thats how variables work. In JAVA I notice this script:

public class TESTRUN {
public static void main(String[] args) {
int x = 0;
int y = x;
System.out.printf("x = %d, y = %d %n", x, y);
x = 9;
System.out.printf("x = %d, y = %d", x, y);
}
}

This yields:
x = 0, y = 0
x = 9, y = 0

So I get that JAVA doesn't understand variables? Or only takes instances of variables? Is there any way to yield a true variable or you always have to update variable relationships?
