使用Java显示MySQL数据库中的所有表？

import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.DatabaseMetaData;

public class GetAllTables {
   public static void main(String[] args) throws SQLException {
      Connection conn = null;
      try {
         try {
            Class.forName("com.mysql.jdbc.Driver");
         } catch (Exception e) {
            System.out.println(e);
         }
         conn = (Connection) DriverManager.getConnection("jdbc:mysql://localhost/test", "Manish", "123456");
         System.out.println("Connection is created succcessfully:");
      } catch (Exception e) {
         System.out.println(e);
      }
      ResultSet rs = null;
      DatabaseMetaData meta = (DatabaseMetaData) conn.getMetaData();
      rs = meta.getTables(null, null, null, new String[] {
         "TABLE"
      });
      int count = 0;
      System.out.println("All table names are in test database:");
      while (rs.next()) {
         String tblName = rs.getString("TABLE_NAME");
         System.out.println(tblName);
         count++;
      }
      System.out.println(count + " Rows in set ");
   }
}
