Thread: user input strings to vectors

Pretty much I have to do this.

I have this.

import java.util.*;
public class Prog1
{
 
public static void main(String args[])
{
 
Vector vec = new Vector(); ]

After that I don't know how to get a user input to be a string and stored into a vector. I know the user input command is "console.readLine." How would i use this command to store the string value as a vector? I know once I get this command to store the values I can use a for loop to allow it to let me store 10 string items.

Here's a neat and simple guide I just found:
How-To-Use Scanner
For the above, what you're after would be towards the bottom of the page mostly.
Additionally, It wouldn't hurt to read the API for scanner.
Scanner (Java 2 Platform SE 5.0)

Scanner (Java Platform SE 6)

Vector (Java Platform SE 6)

No, a Vector is a generic type of thing.
Vector<Object> v = new Vector<Object>();

Vector<Integer> v2 = new Vector<Integer>();

A Vector is kinda like an array but it can be extended until it runs out of room...though don't take it that far....unlike an array which has a fixed size.

A Vector has some method called

for

Vector<T> ;

public T get(int index)
{
return the data at the index...or returns null if invalid index range)
}

public void add(T data, int index)
{
adds data at index or doesn't if you give it a bad index
// Note...you can add data at index size but not more than size or less than 0.
}

public void add(T data)
{
// adds data at last index in Vector
}

public void remove(int index)
{
// removes data at index..or doesn't if it's invalid.
}

public int size()
{
returns the size of Vector
}

Look up Collection on Java API for more details.

A Scanner is used mainly for input...either from a File or from a console.

a classic example is

static Scanner console = new Scanner(System.in);

the variable console is a Scanner object that reads in user input from keyboard

Scanner reader = new Scanner("AFile.txt");

would be an example of a Scanner that read from a file.

Here's how you might deal with Vector problem.

1.) Make a Scanner with System.in as parameter.
2.) Make a Vector<Type> object
3.) Make a for loop that goes from 0 to less than 10.
4.) For each iteration...println telling the user to input the value
5.) Set the value read by the Scanner object to a variable called temp.
{For a String..for instance

String temp = console.nextLine();
}
6.) VectorObject.add(temp);

for (int ir = 0; i <= 10; i++)

and this will execute 11 times not 10.

Please change it to <10.

String temp = console.nextLine();
Is wrong because your Scanner object is called scanner not console.

Secondly, Remove the last bracket from
System.out.println(vec.toString()); ).
