Hi All i am having a python code i have to convert this to java i have placed the code below
import boto3
import sys
import re
import json
def get_kv_map(file_name):
with open(file_name, 'rb') as file:
img_test = file.read()
bytes_test = bytearray(img_test)
print('Image loaded', file_name)
# process using image bytes
client = boto3.client('textract')
response = client.analyze_document(Document={'Bytes': bytes_test}, FeatureTypes=['FORMS'])
# Get the text blocks
blocks=response['Blocks']
# get key and value maps
key_map = {}
value_map = {}
block_map = {}
for block in blocks:
block_id = block['Id']
block_map[block_id] = block
if block['BlockType'] == "KEY_VALUE_SET":
if 'KEY' in block['EntityTypes']:
key_map[block_id] = block
else:
value_map[block_id] = block
return key_map, value_map, block_map
def get_kv_relationship(key_map, value_map, block_map):
kvs = {}
for block_id, key_block in key_map.items():
value_block = find_value_block(key_block, value_map)
key = get_text(key_block, block_map)
val = get_text(value_block, block_map)
kvs[key] = val
return kvs
def find_value_block(key_block, value_map):
for relationship in key_block['Relationships']:
if relationship['Type'] == 'VALUE':
for value_id in relationship['Ids']:
value_block = value_map[value_id]
return value_block
def get_text(result, blocks_map):
text = ''
if 'Relationships' in result:
for relationship in result['Relationships']:
if relationship['Type'] == 'CHILD':
for child_id in relationship['Ids']:
word = blocks_map[child_id]
if word['BlockType'] == 'WORD':
text += word['Text'] + ' '
if word['BlockType'] == 'SELECTION_ELEMENT':
if word['SelectionStatus'] == 'SELECTED':
text += 'X '
return text
def print_kvs(kvs):
for key, value in kvs.items():
print(key, ":", value)
def search_value(kvs, search_key):
for key, value in kvs.items():
if re.search(search_key, key, re.IGNORECASE):
return value
def main(file_name):
key_map, value_map, block_map = get_kv_map(file_name)
# Get Key Value relationship
kvs = get_kv_relationship(key_map, value_map, block_map)
print("\n\n== FOUND KEY : VALUE pairs ===\n")
print_kvs(kvs)
# Start searching a key value
while input('\n Do you want to search a value for a key? (enter "n" for exit) ') != 'n':
search_key = input('\n Enter a search key:')
print('The value is:', search_value(kvs, search_key))
if __name__ == "__main__":
file_name = sys.argv[1]
main(file_name)Could any one convert the above code in java. Kindly help me out to solve this
Thanks in advance
