public class X { public static void main(String [] args) { X x = new X(); X x2 = m1(x); /* Line 6 */ X x4 = new X(); x2 = x4; /* Line 8 */ doComplexStuff(); } static X m1(X mx) { mx = new X(); return mx; } } After line 8 runs. how many objects are eligible for garbage collection?

Only one. After line 8 the original object referred to by x2 is dereferenced and ready for garbage collection. In m1(), mx ignores the object passed as argument and refers to a new object which is returned.
