Help: JAVA encrypted data PHP decryption

Question

java Encrypted ciphertext: iP6nVfCE9Eiw47utJDR6wV6Lhl4xyOgYykub0HUJSZQ=The following is the aes encryption class of java, I hope it can be decrypted with php

package com.mk.api.util;

import java.security.Key;
import java.security.MessageDigest;
import java.util.Arrays;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import javax.xml.bind.DatatypeConverter;

/**

         return encryptedValue;
      } catch (Exception e) {
         e.printStackTrace();
      }
      return null;
   }


   /**

      try {

         Cipher c = Cipher.getInstance(AESTYPE);
         c.init(Cipher.DECRYPT_MODE, key);
         byte[] decordedValue = DatatypeConverter.parseBase64Binary(str);

   private static Key generateKey() throws Exception {

      MessageDigest sha = MessageDigest.getInstance("SHA-1");
      keyValue = sha.digest(keyValue);
      keyValue = Arrays.copyOf(keyValue, 16);
      Key key = new SecretKeySpec(keyValue, AESTYPE);
      return key;
   }
   

}

The format of the above code is messed up
