These operators determine referential equality instead of comparing content.
In most cases, strings should be compared using equals()
,
which does a character-by-character comparison when the strings are different objects.
Example:
void foo(String s, String t) { final boolean b = t == s; }
If t
is known to be non-null, then it's safe to apply the "unsafe" quick-fix and get the result similar to the following:
void foo(String s, String t) { final boolean b = t.equals(s); }
