Silahkan kalo mau menghitung sendiri, berapa nilai maksimalnya🙂. Tetapi berikut ini akan saya berikan program untuk menghitungnya dengan menggunakan bahasa pemrograman java.

import java.io.BufferedReader;
import java.io.FileReader;

public class Euler8 {
    public static void main(String[] args) {
        String temp;
        int num, mul = 1, maks=1;
        try{
            BufferedReader reader = new BufferedReader(new FileReader("1000.txt"));
            if(!(temp=reader.readLine()).equals(null)){
                for(int i=0; i<temp.length()-4; i++){
                    for(int j=i; j<i+5; j++){
                        Character c = new Character(temp.charAt(j));
                        String s = c.toString();
                        num = Integer.parseInt(s);
                        mul *= num;
                    }
					//System.out.println("Perkalian lima ke-"+i+" "+mul);
                    if(maks<mul) maks = mul;
					num = 0;
					mul = 1;
                }
            }
            reader.close();
        }catch(Exception e){
                System.out.println("gagal");
        }
        System.out.println("Nilai terbesar: "+ maks);
    }
}
