here is clear information: When we create a String object using the 'new' operator, it always creates a new object in heap memory. On the other hand, if we create an object using String literal syntax e.g. “Baeldung”, it may return an existing object from the String pool, if it already exists. Otherwise, it will create a new String object and put in the string pool for future re-use. - main difference comes from the point that new String()  always creates a new String object. Also, when we create a String using literal – it is interned. -- https://www.baeldung.com/java-string-pool

Also, when we create a String using literal – it is interned from string pool.. so it returns the reference may not new always......

I think what you want to know is this: https://www.geeksforgeeks.org/strings-in-java/ (Which is highly Google-able if you tried)
