Membuat Program Data Mahasiswa Dengan Menggunakan Array pada Java

contoh program data Mahasiswa menggunakan Array pada Java Programing.
dengan cara menginputkan beberapa data mahasiswa yang di inputkan lebih dari 1


import java.io.*;
class Mahasiswa{
Mahasiswa(){
}
public void tampilMahasiswa() throws IOException{
int b,nim1,nim2,nim3,nim4,nim5,umur1,umur2,umur3,umur4,umur5;
String nama1,nama2,nama3,nama4,nama5,alamat1,alamat2,alamat3,alamat4,alamat5;

(new InputStreamReader(System.in));

System.out.print("Masukkan Nim :");
nim1=Integer.parseInt(br.readLine());

}

}
class DataMahasiswa{
public static void main(String args[])throws IOException{

BufferedReader br = new BufferedReader
(new InputStreamReader(System.in));

Mahasiswa stikom = new Mahasiswa();
stikom.tampilMahasiswa();


}
}
Dengan cara menginputkan nim = nomor induk mahasiswa untuk mencari data mahasiswa yang sudah di registrasi.
