Reusability of Strings in java?

Question

String h = \"hi\";

here we are referencing string h to string literal hi. JVM has a string literal pool to store string literals so we can reuse t

Answer 1

What is meant is that if 20 objects use the same literal String:

private String h = "hi";

all these objects will in fact reference the same String instance in memory. And it doesn't matter, because it's impossible to change the content of the String, since it's immutable. The same instance can thus be shared without problems between objects.
