Mida juhtub, kasutades süntaksit String s1 = "asd"?

Using the syntax String s1 = "asd";:

1. String Pool: The JVM checks if the string literal "asd" already exists in the string pool. The string pool is a special area in the heap where unique string literals are stored to save memory.
2. Object creation:
   • If "asd" already exists in the pool, the variable s1 simply references this existing object.
   • If it does not exist, the JVM creates a new String object in the pool with the value "asd".
3. Reference assignment: The variable s1 gets a reference to the String object in the pool.

Compared to String s2 = new String("asd");, when using a literal, the object can be reused by other references pointing to the same literal, leading to memory optimization.
