import java.io.bufferedreader; import java.io.filenotfoundexception; import java.io.filereader; import java.io.ioexception; public class reader { public static void main(string[] args) { string csvfile = "clients.csv"; bufferedreader br = null; string line = ""; string cvssplitby = ","; try { br = new bufferedreader(new filereader(csvfile)); while ((line = br.readline()) != null) { if(((br.readline().split(cvssplitby))[2]).equals("email@gmail.com")){ string[] data = line.split(cvssplitby); system.out.println("first name: "+data[0]+" last name: "+data[1]+" activity level: "+data[7]); } } } catch (filenotfoundexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } { if (br != null) { try { br.close(); } catch (ioexception e) { e.printstacktrace(); } } } } }
here corrected code fixed problem:
string csvfile = "clients.csv"; bufferedreader br = null; string line = ""; string cvssplitby = ","; try { br = new bufferedreader(new filereader(csvfile)); while ((line = br.readline()) != null) { string[] data = line.split(cvssplitby); if(data[2].equals("samuelfairbrass@icloud.com")){ system.out.println("first name: "+data[0]+" last name: "+data[1]+" email: "+data[2]+" phone number: "+data[3]+" activity level: "+data[7]); } } } catch (filenotfoundexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } { if (br != null) { try { br.close(); } catch (ioexception e) { e.printstacktrace(); } } }
