what is the difference between == ans equals

Answer 1

Main difference between == and equals in Java is that "==" is used to compare primitives while equals() method is recommended to check equality of objects.
Another difference between them is that, If both "==" and equals() is used to compare objects then == returns true only if both references points to same object while equals() can return true or false based on its overridden implementation.
One of the popular cases is comparing two String in Java in which case == and equals() method return different results.
