Я пытаюсь включить индексный номер в мою строку println.Я попытался создать цикл итерации, но он неправильно печатает индексный номер.
package main;
import test.address;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
public class Lab9_main {
// Delimiters used in the CSV file
private static final String COMMA_DELIMITER = ",";
public static void main(String[] args) {
BufferedReader br = null;
try {
// Reading the csv file
br = new BufferedReader(new FileReader("addresses.csv"));
// Create List for holding address objects
ArrayList<address> addressList = new ArrayList<>();
String line;
// Read to skip the header
br.readLine();
// Reading from the second line
while ((line = br.readLine()) != null) {
String[] addressDetails = line.split(COMMA_DELIMITER);
//Save the address details in address object
if(addressDetails.length > 0 ) {
address addy = new address(addressDetails[0], addressDetails[1], addressDetails[2],
addressDetails[3], addressDetails[4], Integer.parseInt(addressDetails[5]));
addressList.add(addy);
}
}
// Lets print the address List
for(address e : addressList) {
System.out.println("The address details in the index....." + e + "....:" + e.getFirstName()
+ "..." + e.getLastName() + "..." + e.getAdd() + "...." + e.getCit() + ".. " + e.getSt()
+ "..." + e.getZip());
}
} catch(Exception ee) {
ee.printStackTrace();
}
finally {
try {
br.close();
} catch(IOException ie) {
System.out.println("Error occurred while closing the BufferedReader");
ie.printStackTrace();
}
}
}
}
Вывод на печать в настоящее время выглядит следующим образом:
The address details in the index.....test.address@61bbe9ba....:John...Doe...120 jefferson st.....Riverside.. NJ...80751
The address details in the index.....test.address@610455d6....:Jack...McGinnis...220 hobo Av.....Phila.. PA...9119
Я хочу индексный номеротображается вместо адреса, например:
The address details in the index.....0....:John...Doe...120 jefferson st.....Riverside.. NJ...80751
The address details in the index.....1....:Jack...McGinnis...220 hobo Av.....Phila.. PA...9119
