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))
