String fileName = "your file";
Wallet ethereumWallet1 =
        EthereumWallet.loadEthereumWallet("your password", new File(fileName));

use private key

Wallet ethereumWallet2 =
        EthereumWallet.loadEthereumWallet("your private key");

Arweave Wallet Creation​

Arweave wallets can be created using java, the official Arweave SDK currently recommended by Arweave, which is installed as follows:

Wallet arweaveWallet = 
        ArweaveWallet.loadArWallet("your file path");

Sdk Client Creation​

ArSeedingService arSeedingService =
        new HttpArSeedingService(arseedUrl, payUrl);
ArSDK arSDK = ArHttpSDK.buildArHttpSDK(arSeedingService, ethereumWallet);

See above for details on payUrl and arseedUrl.
