import java.util.*;

public class LinearSearch {

        public int cari(String[] data, String key) {
                for (int i = 0; i < data.length; ++i) {
                        if (data[i].compareTo(key) > 0)

                        else if (data[i].compareTo(key) == 0)
                                return i;
                }
                return -1;
        }

        public static void main(String[] args) {

                    for (int i = 0; i <= indeksTerakhir; i++)
                         System.out.println("" +i +"    Nama = "+nama[i]+
                         "   \tJenisKelamin = "+JK[i]+"  \tUmur = "+umur[i]);
                }
                LinearSearch search = new LinearSearch();
