I wish this helpful for you getRuntime().exec is for launching an external program. To simple load a file to use in your Java application you can simply treat it like any other file. Indeed if you are using Swing, the ImageIcon constructor will take a String containing the file path as an argument.

Dynamically change an image in a Crystal Report at runtime

I wish this help you At work we do this by pushing the image(s) into the report as fields of a datatable. It's not pretty, but it gets the job done. Of course, this solution requires that you push data into the reports via a DataSet. I've always felt this was a hack at best. I really wish that image parameters were a possibility with CR.
Edit: It's worth noting, if you are binding your crystal report to plain old objects you want to expose a byte[] property for the report to treat that as an image.

WPF Image Dynamically changing Image source during runtime

will help you I have a window with a title on it. When the user selects a choice from a drop down list, the title image can change. The problem is when the image loads, it's a blurred, stretched, and pixelated. These are PNG files I'm working with and they look good prior to setting the source dynamically. , I can think of two things:
First, try loading the image with:

code :

string strUri2 = String.Format(@"pack://application:,,,/MyAseemby;component/resources/main titles/{0}", CurrenSelection.TitleImage);
imgTitle.Source = new BitmapImage(new Uri(strUri2));

Need to replace the existing class in runtime by a dynamically generated and compiled java .classfile at runtime

help you fix your problem URLClassLoader can be useful when you need to load newly generated classes at runtime. Unfortunately, you will not be able to reload the definition of a already loaded class (i.e. reload a class) using URLCLassLoader.

code :

FileInputStream stream = new FileInputStream("Path to your class file");
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int data = stream.read();

while(data != -1){
    buffer.write(data);
    data = stream.read();
}

stream.close();

byte[] classData = buffer.toByteArray();

Dynamically replace Image in Lottie animation at runtime

To fix the issue you can do Managed to do this: the problem was that my After Effects animation had a vector shape, and I was trying to replace this. After I changed the original animation to have a .png instead, I could replace the Image at runtime. Worked just fine.

code :

// First I converted the png I wanted to see at runtime to a bitmap:

Bitmap bitmapImage = BitmapFactory.decodeResource(getResources(), R.drawable.imageBlah);

// I used the lambda: 

lottieAnimationView.setImageAssetDelegate( lottieImageAsset -> bitmapImage);
