Java ask String input with multiple words

Question

HI I am having problem with asking Direct Whole name using Java.

System.out.println("DOCTOR");
System.out.println("Enter ID Number:");
idnumber = scan.next();
System.out.println("Enter Name");
name = scan.next();
System.out.println("Enter Field of Specialization:");
field = scan.next();

System.out.println("ID               " + idnumber);
System.out.println("Name             " + name);
System.out.println("Specializtion    " + field );

and When I enter this information below:

ID = 100 Name = Brandon Sullano

it gives me this result

ID               100    
Name             Brandon    
Specializtion    Sullano

I want Name to be dynamic so I can Input even two words how to do it?
Thanks in Advance..

But do you know how to do it? I saw instead of scan.next will use scan.nextLine() but doesn't work — Brandon Jake Sullano

Explain "does not work." Here at SO, we are a little touchy about that phrase. — D. Ben Knoble

Try this code:

import java.util.Scanner;

public class DoctorDoctor {

    public static void main (String [] args) {

        int idnumber;
        String name, field;

        Scanner sc = new Scanner(System.in);

        System.out.println("DOCTOR");

        /** Assuming ID number is an integer value */
        System.out.print("Enter ID Number: ");
        idnumber = sc.nextInt();
        sc.nextLine(); // This is important, for clearing the new line character

        System.out.print("Enter Name: ");
        name = sc.nextLine();

        System.out.print("Enter Field of Specialization: ");
        field = sc.nextLine();

        System.out.println();
        System.out.printf("%-15s: %d%n", "ID Number", idnumber);
        System.out.printf("%-15s: %s%n", "Name", name);
        System.out.printf("%-15s: %s%n", "Specialization", field);

        sc.close();
    }
}

Example input/output:

DOCTOR
Enter ID Number: 100
Enter Name: Brandon
Enter Field of Specialization: Heart Surgeon

ID Number      : 100
Name           : Brandon
Specialization : Heart Surgeon

Use:

name = scan.nextLine();

Also, if the ID number is an integer, use nextInt() (make sure to also declare idnumber as an int instead of string)

Fixed code:

System.out.println("DOCTOR");
System.out.println("Enter ID Number:");
idnumber = scan.nextInt();
scan.nextLine();

System.out.println("Enter Name");
name = scan.nextLine();
System.out.println("Enter Field of Specialization:");
field = scan.nextLine();

System.out.println("ID               " + idnumber);
System.out.println("Name             " + name);
System.out.println("Specializtion    " + field );

Using just next() will take all input before a space. nextLine() will take all input before return is pressed.

it doesn't work when I run System will jump asking me for Name and skip the Id number

Works fine on my end.

it will ask directly to Name and skip the ID number

Watermel0n Over a year ago

@UnknownOctopus Pro tip: idnumber = scan.nextInt(); needs to have a scan.nextLine() after it. Else, name = scan.nextLine(); will consume the new line character, causing the program to jump to "Enter field of.."

@Watermel0n Edited. Thanks.

Since you say scan.nextLine() "doesn't work", I suggest using BufferedReader.

BufferedReader br=new BufferedReader(new InputStreamReader(System.in);
//in your code:
int idnumber = Integer.parseInt(br.readLine());
String name = br.readLine();
String field = br.readLine();

You have to import java.io.BufferedReader and java.io.InputStreamReader
