Java: ArangoDB: Drop a database

Step 1: Get an instance of ArangoDB.

ArangoDB arangoDB = new ArangoDB.Builder().user(USER_NAME).password(PASSWORD).host(HOST, PORT).serializer(new ArangoJack()).build();

 

Step 2: Get the ArangoDatabase instance for the given database and drop it.

ArangoDatabase arangoDatabase = arangoDB.db(databaseName);
Boolean isDropped = arangoDatabase.drop();

Find the below working application.

 

DatabaseDropDemo.java

package com.sample.app;

import java.util.Collection;

import com.arangodb.ArangoDB;
import com.arangodb.ArangoDatabase;
import com.arangodb.mapping.ArangoJack;

public class DatabaseDropDemo {
  private static final String USER_NAME = "root";
  private static final String PASSWORD = "tiger";
  private static final String HOST = "127.0.0.1";
  private static final int PORT = 8529;

  private static void printDatabases(ArangoDB arangoDB) {
    Collection<String> databases = arangoDB.getDatabases();

    System.out.println("\nAll the databases");
    for (String database : databases) {
      System.out.println(database);
    }
  }

  public static void main(String args[]) {
    // Get an ArangoDB instance
    ArangoDB arangoDB = new ArangoDB.Builder().user(USER_NAME).password(PASSWORD).host(HOST, PORT)
        .serializer(new ArangoJack()).build();

    String databaseName = "testdb";

    boolean isDbCreated = arangoDB.createDatabase(databaseName);

    if (isDbCreated) {
      System.out.println("Database " + databaseName + " created successfully");
    } else {
      System.out.println("Unable to create a database : " + databaseName);
      System.exit(1);
    }

    printDatabases(arangoDB);

    // Drop the databases
    ArangoDatabase arangoDatabase = arangoDB.db(databaseName);
    Boolean isDropped = arangoDatabase.drop();

    System.out.println("\nIs the database " + databaseName + " dropped : " + isDropped);
    printDatabases(arangoDB);

    System.exit(0);

  }

}


Output

Database testdb created successfully

All the databases
_system
testdb

Is the database testdb dropped : true

All the databases
_system
