Salah satu kegunaan dari Metode Searching kita bisa menggunakan untuk pencarian data mahasiswa yang terdiri dari NPM, Nama, Alamat dan pencariannya berdasarkan NPM. Berikut listing program programnya.

<br />
import java.util.Scanner;</p>
<p>public class DataMahasiswa{<br />
	 public static void main(String[ ] args){<br />
		 Scanner in= new Scanner(System.in);<br />
		 //Menentukan Jumlah Data yang akan d Tampung<br />
		 System.out.print(&quot;Jumlah data : &quot;);int N=in.nextInt();<br />
		 //Array untuk menampung Data<br />
		 String npm[ ]=new String[N];<br />
		 String nama[ ]=new String[N];<br />
		 String alamat[ ]=new String[N];</p>
<p>		 //Proses Memasukkan Data<br />
		  for(int i=1;i&lt;=N;i++){<br />
			   System.out.println(&quot;Mahasiswa ke-&quot;+i);<br />
			   System.out.print(&quot;tNPM : &quot;);npm[i-1]=in.next();<br />
			   System.out.print(&quot;tNama : &quot;);nama[i-1]=in.next();<br />
			   System.out.print(&quot;tAlamat : &quot;);alamat[i-1]=in.next();<br />
			   System.out.println();<br />
		  }<br />
		  //Proses Menampilkan Semua Data<br />
		 System.out.println(&quot;nSemua Data Mahasiswa&quot;);<br />
		 System.out.println(&quot;+----+--------------+--------+-----------+&quot;);<br />
		 System.out.println(&quot;| No | NPM | NAMA | ALAMAT |&quot;);<br />
		 for(int i=1;i&lt;=N;i++){<br />
			 System.out.println(&quot;+----+--------------+--------+-----------+&quot;);<br />
			 System.out.println(&quot;| &quot;+i+&quot; | &quot;+npm[i-1]+&quot; | &quot;<br />
			 +nama[i-1]+&quot; &quot;+alamat[i-1]+&quot; |&quot;);<br />
		 }<br />
		System.out.println(&quot;+----+--------------+--------+-----------+n&quot;);<br />
		//Proses Pencarian Data<br />
		int ketemu=0;<br />
		int index[]=new int[N];<br />
		System.out.println(&quot;+ Cari Data Mahasiswa+&quot;);<br />
		System.out.print(&quot;Masukkan NPM : &quot;); String cari=in.next();<br />
		for(int i=0;i<br />
			 if(npm[i].equals(cari)){<br />
				   index[ketemu]=i;<br />
				   ketemu++;<br />
			 }<br />
		}<br />
		//Proses Menampilkan Data yang di Cari<br />
		if(ketemu &gt; 0){<br />
			 System.out.println(&quot;ndata di temukan...&quot;);<br />
			 System.out.println(&quot;+---+--------------+--------+-----------+&quot;);<br />
			 System.out.println(&quot;|No | NPM | NAMA | ALAMAT |&quot;);<br />
			 System.out.println(&quot;+---+--------------+--------+-----------+&quot;);<br />
			 for(int a=1; a&lt;=ketemu; a++){<br />
				  int s=index[a-1];<br />
				  System.out.println(&quot;| &quot;+(index[a-1]+1)+&quot; |<br />
				  &quot;+npm[s]+&quot; | &quot;+nama[s]+&quot; | &quot;+alamat[s]+&quot; |&quot;);<br />
			  }System.out.println(&quot;+---+--------------+--------+-----------+n&quot;);<br />
		 }<br />
		 else{<br />
			   System.out.println(&quot;NPM &quot;+cari+&quot; yang anda cari tidak ada&quot;);<br />
		}<br />
	}<br />
}<br />
