If the string already exists in the pool, a reference to the pooled instance is returned. If the string doesn't exist in the pool, a new string instance is created and placed in the pool.

May 18, 2024 · By understanding the syntax for declaring string literals and practicing with different examples, you can effectively utilize string literals in your Java programs to store and manipulate text-based data.
