For loop, getting two successive files

I am using for loop to get files in a file directory. However, I want to take each file and its successive file as the input of my GetDiffs method. How can I achieve so?

Here is my code:

File folder = new File("/Users/Sam/Desktop/Image");
    for (File fileEntry : folder.listFiles()) {
        if (fileEntry.getName().endsWith(".png"))
       Diffs.GetDiffs( , );
    }

You can use a local variable to store the previous File :

File folder = new File("/Users/Sam/Desktop/Image");
File prev = null;
for (File fileEntry : folder.listFiles()) {
   if (fileEntry.getName().endsWith(".png")) {
       if (prev != null)
           Diffs.GetDiffs(prev, fileEntry);
       prev = fileEntry;
   }      
}
