Why it outputs false in the first case:

{
public static void main(String[] args) {
String hello=new String("hello world");
String hi = new String(hello);

}
}
// Answer: false true

Answer 1

In general both equals() and “==” operator in Java are used to compare objects to check equality but here are some of the differences between the two: ... In simple words, == checks if both objects point to the same memory location whereas .equals() evaluates to the comparison of values in the objects.

Answer 2

Because of "==" operator is used for reference comparison and .equals() method also for reference comparison in Object class but String class override Object class .equals method for content comparison.

Answer 5

->Main difference between .equals() method and == operator is that one is method and other is operator.
->We can use == operators for reference comparison (address comparison) and .equals() method for content comparison. In simple words, == checks if both objects point to the same memory location whereas .equals() evaluates to the comparison of values in the objects.
