Encrypt and decrypt string using AES algorithm using Java

Encrypt and decrypt string or bytes using AES algorithm performed by Java code. below is the code snippet. 

package com.pkm;

import java.security.Key;
import java.security.SecureRandom;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class EncryptUtils {
    private static String algorithm = "AES";
    private static byte[] keyValue = "1111111111111111".getBytes();
    private static SecureRandom iv = new SecureRandom("192837465UTYELBN".getBytes());
    
    public static void main(String[] args) throws Exception {
        String valueToEncrypt = "Some value";
        String encryptedValue = encrypt(valueToEncrypt);
        System.out.println("Encrypted=" + encryptedValue);
        
        String afterDecrypt = decrypt(encryptedValue);
        System.out.println("Decrypted=" + afterDecrypt);
    }

    static String encrypt(String value) throws Exception {
        Key key = generateKey();
        Cipher cipher = Cipher.getInstance(algorithm);
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);
        byte [] encByte = cipher.doFinal(value.getBytes());
        String encString = new BASE64Encoder().encode(encByte);
        return encString;
    }

    static String decrypt(String value) throws Exception {
        Key key = generateKey();
        Cipher cipher = Cipher.getInstance(algorithm);
        cipher.init(Cipher.DECRYPT_MODE, key);
        byte [] decByte64 = new BASE64Decoder().decodeBuffer(value);
        byte [] decByte = cipher.doFinal(decByte64);
        String decString = new String(decByte);
        return decString;
    }

    static private Key generateKey() throws Exception {
        return new SecretKeySpec(keyValue, algorithm);
    }
}

Below is output:

Original=Some value

Encrypted=i4he5mR49eRkWmQRVh12yg==
Decrypted=Some value
