On virtual machines and expected behaviour

Ever tried running this on your ENTERPRISE VIRTUAL MACHINE?
Integer a = 1000;
 Integer b = 1000;
 System.out.println("a == b (1000 == 1000): " + (a == b));

 Integer aa = 100;
 Integer bb = 100;
 System.out.println("aa == bb (100 == 100): " + (aa == bb));
Guess what's the output, run it and report back.

expected output: a bunch of errors.
actual output:
test.java:4: class, interface, or enum expected
Integer a = 1000;
^
test.java:5: class, interface, or enum expected
 Integer b = 1000;
 ^
test.java:6: class, interface, or enum expected
 System.out.println("a == b (1000 == 1000): " + (a == b));
 ^
test.java:8: class, interface, or enum expected
 Integer aa = 100;
 ^
test.java:9: class, interface, or enum expected
 Integer bb = 100;
 ^
test.java:10: class, interface, or enum expected
 System.out.println("aa == bb (100 == 100): " + (aa == bb));
 ^
6 errors

after fixing those errors:
expected output:
a == b (1000 == 1000): false
aa == bb (100 == 100): false

actual output:
a == b (1000 == 1000): false
aa == bb (100 == 100): true

As is:
Needs libraries and public class frame

With necessary corrections:
a == b (1000 == 1000): false
aa == bb (100 == 100): true
But this is not correct because you fudged the object constructor for the wrapper class.

After corrections to the Integer wrapper class (e.g., Integer a = new Integer("1000");):
a == b (1000 == 1000): false
aa == bb (100 == 100): false

Essentially your shoddy coding failed, not the language.  Good day.
