1. Develop a class TelephoneIndex with two String objects as members.

import java.util.Scanner; class TelephoneIndex{ String name, phone; TelephoneIndex(){ } void getData(String Cname, String pno) { // System.out.println("set data"); this.name = Cname; this.phone = pno; } void display(String Cname, String pno) { System.out.println(name + " " + phone); } void findData(String cname){ if(name.startsWith(cname)) { display(name,phone); } } } class Main{ public static void main(String args[]){ Scanner in = new Scanner(System.in); int N = in.nextInt(); in.nextLine(); TelephoneIndex[] ti = new TelephoneIndex[N]; String contactName, phoneNum; for(int i =0;i<N;i++) { //System.out.println("get contactName"); contactName = in.nextLine(); //System.out.println("get phoneNum"); phoneNum = in.nextLine(); ti[i] = new TelephoneIndex(); ti[i].getData(contactName, phoneNum); //System.out.println("output name phone" + ti[i].name + " " + ti[i].phone); } String findName = in.nextLine(); for(int i =0;i<N;i++){ // t = new TelephoneIndex(); ti[i].findData(findName); } } }
