There are multiple ways to do that. The code for these will require modification based on your needs, so I will put in some pointers to the high level methods and libraries:

You can directly use GUI-automation tools such as pyautogui to press Alt+PrntScreen and transfer the data from clipboard into a variable (http://pyautogui.readthedocs.io/en/latest/keyboard.html#keyboard-keys)
You can use pywin32 and PIL to grab the image of a certain window (How to Get a Window or Fullscreen Screenshot (without PIL)?)
You can use ImageMagick to grab screenshots of a single window (https://www.imagemagick.org/discourse-server/viewtopic.php?t=24702)
You can use pyautogui.locateOnScreen("Sceenshot.PNG") to find the tuple which will contain the boundaries of the window for your java app. Then you can pass it to your function img.ImageGrab.grab(bbox)

A example to get the content(screenshot) of a specific window with the help of the pygetwindow module.

import pygetwindow
import time
import os
import pyautogui
import PIL

# get screensize
x,y = pyautogui.size()
print(f"width={x}\theight={y}")

x2,y2 = pyautogui.size()
x2,y2=int(str(x2)),int(str(y2))
print(x2//2)
print(y2//2)

# find new window title
z1 = pygetwindow.getAllTitles()
time.sleep(1)
print(len(z1))
# test with pictures folder
os.startfile("C:\\Users\\yourname\\Pictures")
time.sleep(1)
z2 = pygetwindow.getAllTitles()
print(len(z2))
time.sleep(1)
z3 = [x for x in z2 if x not in z1]
z3 = ''.join(z3)
time.sleep(3)

# also able to edit z3 to specified window-title string like: "Sublime Text (UNREGISTERED)"
my = pygetwindow.getWindowsWithTitle(z3)[0]
# quarter of screen screensize
x3 = x2 // 2
y3 = y2 // 2
my.resizeTo(x3,y3)
# top-left
my.moveTo(0, 0)
time.sleep(3)
my.activate()
time.sleep(1)

# save screenshot
p = pyautogui.screenshot()
p.save(r'C:\\Users\\yourname\\Pictures\\\\p.png')

# edit screenshot
im = PIL.Image.open('C:\\Users\\yourname\\Pictures\\p.png')
im_crop = im.crop((0, 0, x3, y3))
im_crop.save('C:\\Users\\yourname\\Pictures\\p.jpg', quality=100)

# close window
time.sleep(1)
my.close()

r/learnpython on Reddit: How i can screenshot a specific window?

August 12, 2021 -

First time posting here, i am very new to python, but i want to make a screenshot of a specific window, instead of all of the screen, this is my current code that makes a screenshot of all of the screen

from PIL import ImageGrab
screen =  ImageGrab.grab(bbox=(0,0,1366,768))
screen.save('grabbed.png')
print("done")

I searched on internet but the only solution that i found was to get the size and position of the selected window and then take a screenshot with those info so it only gets that window, howewer if there is something covering that window it wont take the screenshot correctly... is it atleast possible?

I may have made exactly what you're looking for. With a tkinter interface. The window has to be active unfortunately but this tool does that for you. Should grab all of the same type of window, as in take a screenshot of each pdf open for example... Windows cannot be minimized if I remember correctly. https://github.com/Reuben3901/Windows_Window_Screenshot/blob/master/WindowScreenshotButtons.py

You can use PyGetWindow to get the info of a window based on its name, and then use your screenshot library of choice to get that part of the screen (personally I use mss because it’s fast and cross-platform).
