It represents the result of executing a SQL `SELECT` statement and provides methods for accessing the retrieved rows and columns. A `ResultSet` acts as a bridge between the relational data stored in a database and Java application code. Instead of directly manipulating database records, a Java program can use the `ResultSet` object to navigate through query results and retrieve individual values in an organized manner. The lifecycle of a `ResultSet` begins when a JDBC statement is executed. A connection is first established with the database using the `Connection` interface. A `Statement`, `PreparedStatement`, or `CallableStatement` is then created from the connection.
