Program Casting Java

 Mumpung lagi ada niat ngoding :D

/**
 * Title    : Program casting tipe data

public class DemoCasting {

    /** Main Method */
    public static void main(String[] args){
   
    // Narrowing
        double nilaiDouble = 3000.56d;
    long m = (long)nilaiDouble;
    int j = (int)m;
    byte x = (byte)j;
   
    // Widening
    byte nilaiByte = -72;
    int i = (int)nilaiByte;
    long p = (long)i;
    double z = (double)p;
   
    System.out.println("\nPROGRAM CASTING TIPE DATA");
    System.out.println("---------------------------\n");
   
    System.out.println("NARROWING");
    System.out.println("Nilai asli double" + "\t" + nilaiDouble);
    System.out.println("Proses Narrowing long" + "\t" + m);
    System.out.println("Proses Narrowing int" + "\t" + j);
    System.out.println("Proses Narrowing byte" + "\t" + x);
   
    System.out.println("\nWIDENING");
    System.out.println("Nilai asli byte" + "\t" + nilaiByte);
    System.out.println("Proses Widening int" + "\t" + i);
    System.out.println("Proses Widening long" + "\t" + p);
    System.out.println("Proses Widening double" + "\t" + z);
   
    }
}

Seperti print screen nya, douzo... :)
