In Java, which method is commonly used for executing SQL queries in JDBC?Question 13Answera.executeQuery()b.executeUpdate()c.execute()d.runQuery()

The method commonly used for executing SQL queries in JDBC is a.executeQuery(). Here are the steps to do it:

1. First, you need to establish a connection to the database you want to query. You can do this using the DriverManager.getConnection() method.

2. Once the connection is established, you can create a Statement object using the Connection.createStatement() method.

3. Now, you can execute your SQL query using the Statement.executeQuery() method. This method takes the SQL query as a parameter and returns a ResultSet object which contains the results of the query.

4. Finally, you can iterate through the ResultSet to retrieve the data.

Here is a simple example:

import java.sql.*;

public class Main {
  public static void main(String[] args) {
    try {
      // Step 1: Establishing a Connection
      Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");

      // Step 2: Create a statement
      Statement stmt = conn.createStatement();

      // Step 3: Execute the query
      ResultSet rs = stmt.executeQuery("SELECT * FROM mytable");

      // Step 4: Process the ResultSet
      while(rs.next()){
        System.out.println(rs.getString("columnname"));
      }
    } catch (SQLException e) {
      e.printStackTrace();
    }
  }
}

In this example, replace "jdbc:mysql://localhost:3306/mydatabase", "username", "password", "SELECT * FROM mytable", and "columnname" with your actual database URL, username, password, SQL query, and column name respectively.
