konversi jarak pada Netbean

Diketahui perhitungan konversi jarak seperti gambar dibawah ini!!

TAHAP 1. Ada permintaan input dengan tampilan sbb 

 

TAHAP 2. Setelah diisi nilainya, mis : 200, maka akan ada permintaan satuannya

 

Scriptnya seperti dibawah ini...

public static void main(String[] args) {
         double nilai = 0;
        String konv="";
        BufferedReader nila = new BufferedReader(new InputStreamReader(System.in));
        BufferedReader kon = new BufferedReader(new InputStreamReader(System.in));
      
        try {
        System.out.println("masukkan nilai : "); 
        nilai =Integer.parseInt(nila.readLine());
        
        }
    catch( IOException e ){
      System.out.println("Error!");
      }
      
        try {
          
        System.out.println("masukkan satuan : "); 
        konv =kon.readLine();
        System.out.println("=======================");
        System.out.println("Berikut Hasilnya :");
        System.out.println("=======================");
         if("KM".equals(konv)){// proses
    System.out.println("MM ="+nilai*1000000);    System.out.println("CM ="+nilai*100000);    System.out.println("DM ="+nilai*10000);    System.out.println("M ="+nilai*1000);    System.out.println("DaM ="+nilai*100);    System.out.println("HM ="+nilai*10);    System.out.println("KM ="+nilai/1);          }
       else if("KM".equals(konv)){// proses

          }
        } 
    catch( IOException e ){
      System.out.println("Error!");
      }
       // TODO code application logic here
      
    }}

Dan hasilnya menjadi seperti ini
