how to accept string array in java using bufferedreader

Question

public static void accept_name( String[] name, int[] r)
{

   InputStreamReader isr = new InputStreamReader(System.in);
   BufferedReader ab = new BufferedReader(isr);
    r = new int[40];
    name = new String[40];
    for(int i=0;i<40;i++)
    {
        System.out.println("Enter the name of students");
        name[i] = ab.readLine();
    }             
}

i am having a problem in name[i] = ab.readLine();

i don't understand what the problem is.

Answer 1

When using Input\Output stream, an IOException is expected, define that it might throw that kind of exception:

public static void accept_name (String[] name, int[] r) throws IOException
{
   InputStreamReader isr = new InputStreamReader(System.in);
   BufferedReader ab = new BufferedReader(isr);

    r = new int[40];
    name = new String[40];

    for(int i=0;i<40;i++)
    {
        System.out.println("Enter the name of students");
        name[i] = ab.readLine();
    }             
}
