i have directory several text files in it, each of contains line of text delimited commas. expecting find 4 tokens read each file while creating string array. so, normal line in text file this:
cat,dog,876358293472,884459654596 but want account files not formed expect. or if file empty. instance, file might have this:
cat,dog, or
cat,0000000000000 i have code handle token length not sure how account cases file isn't formatted expect. here's have far:
while((line = br.readline()) != null) { try { string [] tokens = line.trim().split(","); if (tokens.length != 4) { return null; } are there other checks should in addition 'token.length'?
you need call split(",",-1), prevent empty fields merging:
"a,b,c,".split(",") --> ["a", "b", "c"] "a,b,c,".split(",",-1) --> ["a", "b", "c", ""] if care getting 4 strings, test fine.
