Program 3 A class called Series has been defined to generate the following series:
1, 12, 123, 1234, 12345
The description of the class is given below:
Data Member
int t : To store each term
Series() : Constructor to initialise t to 0
void print(int n) : Using recursive technique to print the terms of the series
1 import java.util.*;
2 public class Series
3 {
4 int t;
5 public Series()
6 {
7 t=0;
8 }
9 void print(int n)
10 {
11 if(n>5)
12 System.out.println();
13 else
14 {
15 t=t*10+n;
16 System.out.print(t+" ");
17 print(n+1);
18 }
19 }
20 public static void main()
21 {
22 Series sr = new Series();
23 sr.print(1);
24 }
25 }
The output of the preceding program is as follows:
1 12 123 1234 12345
