My program is supposed to ask the user for firstname, lastname, and phone number till the users stops. Then when to display it asks for the first name and does a search in the text file to find all info with the same first name and display lastname and phones of the matches.
import java.util.*;
import java.io.*;
import java.util.Scanner;
public class WritePhoneList
{
public static void main(String[] args)throws IOException
{
BufferedWriter output = new BufferedWriter(new FileWriter(new File(
"PhoneFile.txt"), true));
String name, lname, age;
int pos,choice;
try
{
do
{
Scanner input = new Scanner(System.in);
System.out.print("Enter First name, last name, and phone number ");
name = input.nextLine();
output.write(name);
output.newLine();
System.out.print("Would you like to add another? yes(1)/no(2)");
choice = input.nextInt();
}while(choice == 1);
output.close();
}
catch(Exception e)
{
System.out.println("Message: " + e);
}
}
}
Here is the display code, when i search for a name, it finds a match but displays the last name and phone number of the same name 3 times, I want it to display all of the possible matches with the first name.
import java.util.*;
import java.io.*;
import java.util.Scanner;
public class DisplaySelectedNumbers
{
public static void main(String[] args)throws IOException
{
String name;
String strLine;
try
{
FileInputStream fstream = new FileInputStream("PhoneFile.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
Scanner input = new Scanner(System.in);
System.out.print("Enter a first name");
name = input.nextLine();
strLine= br.readLine();
String[] line = strLine.split(" ");
String part1 = line[0];
String part2 = line[1];
String part3 = line[2];
//Read File Line By Line
while ((strLine= br.readLine()) != null)
{
if(name.equals(part1))
{
// Print the content on the console
System.out.print("\n" + part2 + " " + part3);
}
}
}catch (Exception e)
{//Catch exception if any
System.out.println("Error: " + e.getMessage());
}
}
}
