so on 7:00, is String name = "navin"; just a simplified way of typing String name = new String("navin"); ? Do they both work the exact way and mean the same thing?

Yes

@taraprasadsarangi8124 7 ай бұрын

they are different String name = "navin"; is a string literal String name = new String("navin"); is an object even though they have the same value

@@hardwaregeek995 two objects. first one creates an object in an area in heap memory called string pool but when you use new keyword to create a string, you are telling the jvm to create string object in another area of heap maybe general part of heap but not in string pool.

String s = new String ("abc"); String S2 = "abc"; How many objects will be created in the heap memory?

@tommyhsiao2663 2 ай бұрын

first line will check if "abc" in the string pool (special space in the heap memory), if it is not there create it. And new String ("abc") will create an object in the heap. Second line will check if "abc" literal is in the string pool, we have created it in the first line, so S2 will just point (reference) to that "abc". Total two objects are created, one is in the string pool, one is in the general heap memory.
