Calling Java From Python

This article discusses the process of calling Java code from Python using jpype or pyjnius libraries, allowing for seamless integration between the two languages. Additionally, it covers the usage of the com.github.pemistahl.lingua.api library to detect the language within a given text.

using jpype or pyjnius

sample code for jpype:

from jpype import *
import jpype.imports # this is needed! shit.
addClassPath("/root/Desktop/works/pyjom/tests/karaoke_effects/classpath/lingua.jar")
startJVM(getDefaultJVMPath())
java.lang.System.out.println("Calling Java Print from Python using Jpype!")
from com.github.pemistahl.lingua.api import *
# detector = LanguageDetectorBuilder.fromAllLanguages().withLowAccuracyMode().build()
detector = LanguageDetectorBuilder.fromAllLanguages().build() # 3.5GB just for detecting language! it is somehow crazy.
sample = 'hello world'
result = detector.detectLanguageOf(sample)
print(result, type(result)) # <java class 'com.github.pemistahl.lingua.api.Language'>
# but we can convert it into string.
strResult = str(result)
print(strResult, type(strResult))
import math
print("CALLING MATH: %d" % math.sqrt(4))
shutdownJVM()

sample for pyjnius:

import jnius_config
# jnius_config.add_options('-Xrs', '-Xmx4096')
jnius_config.set_classpath('.', "/root/Desktop/works/pyjom/tests/karaoke_effects/classpath/lingua.jar")
import jnius
jnius.autoclass('java.lang.System').out.println('Hello world')
detector = jnius.autoclass('com.github.pemistahl.lingua.api.LanguageDetectorBuilder').fromAllLanguages().build()
sample = 'hello world'
result = detector.detectLanguageOf(sample)
print(result, type(result))
# breakpoint()
strResult = result.toString()
print(strResult, type(strResult))
