Strings are immutable. What happens if we assign another value to a string reference?

Question

Accepted Answer

Assigning another value to a string reference creates a new string object in memory.

Assigning a new value to a string reference creates a new string object in memory
The original string object remains unchanged
The new value is stored in a different memory location
The old value may be garbage collected if there are no other references to it

Accepted Answer

When ever we assign the value to String it will create a pool in a SCP(Spring Constant pool) and Heap memory. when we try to add another value it will create a new String Object in both SCP and Heap.
hence String is a immutable.

Accepted Answer

In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default it uses the equals(Object o) method of the closest parent class that has overridden this method.
