    Scanner in = new Scanner(System.in);
    for(int i=0;i<this.names.length;i++){
        System.out.println("Enter Name:");
        this.names[i] =in.next();
        System.out.println("Enter Phone Number:");
        this.telephones[i]=in.next();//here start rising exception 
    }
    in.close();

I have created the same scenario as you explained but the strange thing is that I am not getting any such exception. Please have a look at the code below

public class TestScanner {
    String names[] = new String[10];
    String telephones[] = new String[10];

    public static void main(String a[]) {

        TestScanner p = new TestScanner();

        Scanner in = new Scanner(System.in);
        for (int i = 0; i < p.names.length; i++) {
            System.out.println("Enter Name:");
            p.names[i] = in.next();
            System.out.println("Enter Phone Number:");
            p.telephones[i] = in.next();// here start rising exception
        }
        in.close();

    }
}

Output

Enter Name:
test1
Enter Phone Number:
123456
Enter Name:
test2
Enter Phone Number:
456789
Enter Name:
