Belajar buat input program di java

import java.util.Scanner;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
public class input{
public static void main(String [] args){
BufferedReader dataIn = new BufferedReader (new InputStreamReader(System.in));
Scanner input = new Scanner(System.in);
String name = " ";
int nilai;
System.out.print("Silahkan masukkan nama anda :");
try {
name = dataIn.readLine ();
}
catch (IOException e){
System.out.println("error");
}
System.out.print("masukkan nilai anda (0-100):");
nilai = input.nextInt();
if(nilai>=70){
System.out.println("selamat, anda lulus ! !");
System.out.println("=) ");
}
else if ((nilai<=70)&&(nilai>=60)){
System.out.println("Anda lulus dengan syarat! ! ! !");
System.out.println(" <.> ");
}
else {
System.out.println("maaf anda gagal,silahkan coba lain kale ya");
System.out.println("T_T");
}
if(nilai>100){
    System.out.println("Maap,anda salah menginput nilai");
    System.out.println(">.<");
}
System.out.println("Nama anda adalah: "+name);
System.out.println("Nilai anda adalah: "+nilai);
}
}
