[SOLVED] I am trying to select the last index of a string after splitting an image name from imageJ. I know in python we can do string[-1]

I am trying to select the last index of a string after splitting an image name from imageJ. I know in python we can do string[-1]

imageName=getTitle(); #This returns a string with the entire path of where the image is.

image1 = split(imageName,"/"); #splits the image where "/" is. Based on path, this varies in length

image = image1[1]; #I want the last one but it will not always be the nth index.

Solution

split() returns an array. In your example you assign the array to image1 so you can find the length of the array using image1.length. Arrays in ImageJ macro language are 0-based so you need to subtract 1 to find the last element.

imageName=getTitle(); #This returns a string with the entire path of where the image is.
image1 = split(imageName,"/"); #splits the image where "/" is. Based on path, this varies in length
image = image1[image1.length - 1]; #last element.

Note that splitting using / will work on mac but not Windows.

My answer is directed at your indexing question. If you simply want the file name without the path, Take a look at File.name and File.nameWithoutExtension for more straightforward ways to get what you need.
