Java Scrip Sederhana

• Menghitung Luas Lingkaran

import java.util.Scanner;

public class LuasLingkaran {


public static void main(String[] args){
Scanner input = new Scanner(System.in);

System.out.println("Luas Lingkaran");
System.out.print("masukan jari-jari=");

int r = input.nextInt();
double pi=3.14;
System.out.print("Luas Lingkaran ="+ (pi*r*r));

}
}

• Menghitung Luas Segitiga

import java.util.Scanner;

public class segitiga{

public static void main(String [] args){

Scanner input = new Scanner(System.in);

System.out.print("masukan alas = ");

        int s = input.nextInt();

System.out.print("masukan Tinggi = ");

int t = input.nextInt();

        double a=0.5;

        System.out.print("Luas Segitiga    = "+ (a*s*t));

}

}
