Condition or function to verify if a file is missing when opening files sequentially in ImageJ

I'm using an ImageJ macro that opens and processes a group of images from several samples sequentially named - e.g. sample1_image1.tif, sample1_image2.tif, sample2_image1.tif, (...). I'm using a loop to increment both sequences for the samples and for the images.

for (i=0; i<samplenumber.length; i++) // Counter of the samples
    {
    imgnumber = imgspersample[i];
    j=0;
    for (j=0; j<imgnumber; j++) // Counter of the images for a given sample
        {
        k = j + 1;
        file = "sample"+samplenumber[i]+"_image"+k+".tif";
        path = directory+file;
        // Opening, converting and thresholding the image
        open(""+path+"");

However, some of the samples might be missing and an error occurs when the macro tries to open an image that doesn´t exist, breaking the loop. Is there any function or condition that can be added so the loop is not broken when a sample is absent?

For example: if sample 2 is missing, the macro opens and processes all images from sample 1, recognizes that there are no images for sample 2, and then jumps to sample 3?

Maybe considering the macro function "File.exists(path)" helps?
