How to use dispose to release resources in java?

Question

I have an attached code and its exception maybe it not relevant in Sololearn discussions or questions but it a problem I'm facing hoping fellow programmer can help me with. The code is based on Tesseract tess4j version 4.5.4 in java 8.

I take screenshot using BufferedImage. On average the screenshot is taken every 5 seconds daily then read image text for every screenshot taken. The images are not saved on file.

For now I'm testing this code on a virtual machine which I'm running it for two weeks consecutively and everything is working fine until the 3th or 4th day of testing. I then get the the attached exception.

When I use the "dispose" to dispose of the instance and start a new one. The Eclipse system says "create dispose method" does this method not internally available?

Answer 1

You declared solo dispose may you need to write
object.dispose();

A other thing is dispose() comes from javax.swing.JFrame lib so maythis just work with a JFrame window
Beside that you didnt display your img somewhere so i believe you didnt need to dispose if you want „delete“ is just asign the variable as null or asign a new value to it

Hopefully that helps
Happy coding ✌️😉
