When using the syntax String s1 = "asd";, the following happens:

  1. The JVM checks the String Pool (a special memory area in the heap) to see if the string literal "asd" already exists.
  2. If "asd" already exists in the pool, the variable s1 references the existing object in the pool.
  3. If "asd" does not exist in the pool, then:
    • A new String object with the value "asd" is created in the pool.
    • The variable s1 references this newly created object.

This mechanism is called String Interning and helps save memory by avoiding the creation of duplicate identical string literals.
