The correct answer is C. 5 4 5 6. Option C (5 4 5 6) is correct because i is a static variable, meaning it belongs to the class itself, not to any individual object. When x2.i = 5 executes, it overwrites the earlier x1.i = 3 assignment - both references point to the same single memory location. Since j is an…

class X {

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;

Explanation

Option C (5 4 5 6) is correct because i is a static variable, meaning it belongs to the class itself, not to any individual object. When x2.i = 5 executes, it overwrites the earlier x1.i = 3 assignment - both references point to the same single memory location. Since j is an instance variable, each object keeps its own copy: x1.j stays 4 and x2.j stays 6.

Why the distractors fail:

A (3 4 5 6) - wrongly assumes x1.i retains 3 after x2.i is set; ignores that static fields are shared across all instances.
B (3 4 3 6) - also misreads static sharing, and incorrectly shows x2.i as 3 rather than the final assigned value of 5.
D (3 6 4 6) - appears to swap the j values and misapplies static behavior entirely; no assignment ever puts 3 or 4 into i at the point of printing.

Memory tip: Think "Static = Shared, Instance = Individual." Whenever you assign to a static field - regardless of which reference you use (x1.i or x2.i) - you're writing to one class-level slot, so the last write always wins for everyone.
