Is it possible when comparing two strings with '==' returns true but return false with '.equals' in java

Question

I'm bit confused about the difference between == and .equals, I been searching for answers but still not quite clear. So, I'm wondering is there an example code can demonstrate that when comparing two strings, == and .equals return different results.

Answer 1

You are asking two distinct questions here. There isn't an example where == returns true but equals returns false. That is not possible. Because (as an optimization) equals checks for reference identity. But even if it did not, it does test for value identity (and that would be the same).

However, there are lots of examples where == returns false but equals returns true. Because == tests references. One trivial example,

String a = "A";
String b = new String(a);
System.out.println(a == b);
System.out.println(a.equals(b));
