我怎样才能使“，” in.txt 文件之后的所有内容都将被单独检查:)？

Question

I need to improve this code that will read from a text file named file.txt

sergy,many,mani,kserder

I would like to use this form:

file = login.getText();
if (file.equals("sergy"))

I just need to do something that will read everything in the text file separately and ignoring "," sign, or something else other than "," sign.

You could split the string by the , character and check if any of the array's elements are equal to the value you're looking for:

file = login.getText();
if (Arrays.asList(file.split(",")).contains("sergy")) {
    // do something...
