Array problem

  Asked By: John    Date: Nov 28    Category: Java    Views: 893
  

Here's the problem:
I have an array. Let's just say the the array is

String[] StudName = new String[5];

I wanna set 5 value to the StudName array FROM console..

FYI, i already know how to input data from the console through BufferedReader..
Right?

What i want to ask are :
-how to SET that value into the array(FROM CONSOLE)?
-how to STORE that value in the array, so that, when I input another value from
console
the previous value won't be overrided?

First, try to get an object of the value from the console. (you already
know how)
Then put the object into the array.

StudName[3] = stud1Object;

Basically you put it in different spots in the array.

StudName[3] = stud2Object; // stud1 will be replaced.

Try my sample program:

import java.io.*;


class InputArray
{
public static void main (String[] args) throws Exception
{
String[] sample = new String[5];
input(sample);
display(sample);
}


public static void input  (String[] args) throws Exception
{
BufferedReader in = new BufferedReader (new InputStreamReader
(System.in));

System.out.println ("Enter 5 values of the String array: ");

int i;

for (i = 0; i < args.length; i++)
{
args[i] = in.readLine();
}
}

public static void display (String[] args)
{
System.out.println ("\nDisplaying the values: ");

int i;

for (i = 0; i < args.length; i++)
{
System.out.println (args[i]);
}
}
}
