Looping pada Netbeans

Menggunakan class For

public class For{

                public static void main(String[] args){

                for (int i=2; i<=10; i+=2)

                                System.out.print(i+” “);

}

}

Hasilnya

2 4 6 8 10

Menggunakan class While

public class While {

                public static void main(String[] args){

                int n=3;

                while(n<20)

                {

                                System.out.println(n+ “ “); n+=3;

                }

                }

}

Hasilnya : 3 6 9 12 15 18

Cotoh program for dengan hasil jumlahnya

public class For {

public  stattic void main(String[] args){

int b=0;

for(int i=1; i<6; i++){

                int j=i*2;

                System.out.print(j+”+”);

                b=b+j;

                if(j==10){

                                System.out.print(“=”);

                                System.out.print(b);

                }

}

}

Hasil

2+4+6+8+10+=30

contoh 2 for dengan hasil jumlah

public class For {

    public static void main (String[] args)

    {

        int i;

        int jum=0;

            for(i=2;i<=10;i+=2){

            System.out.print(i+"+");

            jum=jum+i;

        }

        System.out.print("="+jum);

    }

}
