This is basic enough to practically be a CS assignment; even if not, it's not doing you any learning favours to tell you much about how to do any of this. Think the problem though, and decompose it. You have that file, and assume it's been created by a save method operating on a list of rectangle objects. Now you need to read it - find the Java packages and classes that have to do with reading from text files. Determine how to read line by line from such a file. Either operate on each line as you read it, or store the lines to do that as a second step. Decide how you'll split each line into 4 text representations of numbers, and how you'll convert each into a number. Do you even have a rectangle class ready to go? AHS
