1. Program Input Menghitung Jarak Lintasan Peluru

Buat dulu file Peluru.java lalu masukkan kode berikut:

public class Peluru {

    public static void main(String[] args) {

        double kecepatan, sudut, jarak;

        kecepatan = 32;

  sudut = 40;

  jarak = 2 * kecepatan * kecepatan *

      Math.sin(Math.toRadians(sudut)) *

   Math.cos(Math.toRadians(sudut)) / 9.8;

        System.out.println("Jarak: " + jarak);

    }

}

import java.util.Scanner;

public class Palindrom {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        System.out.print("Masukkan kata: ");

        String kata = input.nextLine();

        char[] huruf = kata.toCharArray();

        String kata2 = "";

        for (char c : huruf) {

            kata2 = c + kata2;

        }

        if (!kata.equals(kata2)){

            System.out.print("Bukan ");

        }

        System.out.print("Palindrom");

    }

}

3. Program untuk menghitung selisih hari 

Buat file bernama Tanggal.java lalu masukkan kode berikut:

import java.time.LocalDate;

import java.time.format.DateTimeFormatter;

import java.time.temporal.ChronoUnit;

public class Tanggal{

public static void main(String[] args){

    

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");

    

    String firstDate = "15/12/2008";

    String secondDate = "18/12/2008";

    

    LocalDate date1 = LocalDate.parse(firstDate, formatter);

    

    LocalDate date2 = LocalDate.parse(secondDate, formatter);

    

    long daysBetween = ChronoUnit.DAYS.between(date1,date2);

    

    if(daysBetween > 0)

    {

        System.out.println("Tanggal sekarang : " + firstDate);

        System.out.println("Tanggal nanti : " + secondDate);

        System.out.println("Selisih hari : " + daysBetween);

        }

    }

}
