i'm @ loss , have no idea how fix this. see errors or why cannot read in split[4]? why copying what's in int appt value?
@ jamie i'm not able understand how getting output because printing object not values. have changed nothing such in code , working fine me. might have missed small. use below code , able desired output.
import java.io.file; import java.io.filenotfoundexception; import java.util.arraylist; import java.util.scanner; public class readinginputincorrectly { public static void main(string[] args) throws filenotfoundexception { arraylist<customer> customerlist=new arraylist<>(); file customer = new file("path cus.txt file"); scanner readcustomer = new scanner(customer); while (readcustomer.hasnextline()) { string line = readcustomer.nextline(); string delims = ", "; string[] split = line.split(delims); int arr = integer.parseint(split[0]); int ser = integer.parseint(split[1]); int qui = integer.parseint(split[2]); int appt = integer.parseint(split[3]); int appl = integer.parseint(split[4]); customer newcustomer = new customer(arr, ser, qui, appt, appl); customerlist.add(newcustomer); system.out.println(newcustomer.num1+", "+newcustomer.num2+", "+newcustomer.num3+", "+newcustomer.num4+", "+newcustomer.num5+", "); } readcustomer.close(); } } class customer{ int num1,num2,num3,num4,num5; customer(int num1,int num2,int num3,int num4,int num5){ this.num1=num1; this.num2=num2; this.num3=num3; this.num4=num4; this.num5=num5; } }
output
