Given: public class X { static int i; int j; public static void main(String[] args) { X x1 = new X(); X x2 = new X(); x1.i = 3; x1.j = 4; x2.i = 5; x2.j = 6; System.out.println( x1.i + " "+ x1.j + " "

This would be the case if `i` was also an instance variable, meaning `x1.i` and `x2.i` were independent.

This incorrectly shows `x2.i` retaining the value of `x1.i` from an earlier assignment, ignoring the static nature of `i`.

The `i` variable is declared as `static`, meaning there is only one copy shared by all instances of the `X` class. When `x2.i = 5` is executed, it updates the single static `i` to 5, affecting both `x1.i` and `x2.i`. The `j` variable is an instance variable, so `x1.j` remains 4 and `x2.j` becomes 6.

This mixes up the values of `j` or implies incorrect assignments for either static or instance variables.
