How to get all table names from a database using JDBC?
You can get the list of tables in the current database in MySQL using the SHOW TABLES query.
Show tables;
Following JDBC program retrieves the list of tables in the database by executing the show tables query.
Example
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class ListingTables {
public static void main(String args[]) throws Exception {
//Registering the Driver
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//Getting the connection
String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
System.out.println("Connection established......");
//Creating a Statement object
Statement stmt = con.createStatement();
//Retrieving the data
ResultSet rs = stmt.executeQuery("Show tables");
System.out.println("Tables in the current database: ");
while(rs.next()) {
System.out.print(rs.getString(1));
System.out.println();
}
}
}Output

Or, You can use the getTables() method of the DatabaseMetaData interface.
Example
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class RS_getTables {
public static void main(String args[]) throws Exception {
//Registering the Driver
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//Getting the connection
String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
System.out.println("Connection established......");
//Retrieving the meta data object
DatabaseMetaData metaData = con.getMetaData();
String[] types = {"TABLE"};
//Retrieving the columns in the database
ResultSet tables = metaData.getTables(null, null, "%", types);
while (tables.next()) {
System.out.println(tables.getString("TABLE_NAME"));
}
}
}Output
