1. Program Menghitung Keliling Lingkaran


import java.io.*;
class kelilinglingkaran
{
public static void main(String[] args) throws IOException {
InputStreamReader key = new InputStreamReader(System.in);
BufferedReader input = new BufferedReader(key);
String rad;
double rads, luas, kel, phi = 3.14;
System.out.print("Masukan Nilai Radius :");
rad = input.readLine();
rads = Double.parseDouble(rad);
luas = phi * rads;
kel = 2 * phi * rads;
System.out.println("Hasil Perhitungan");
System.out.println("Luas Lingkaran :" + luas);
System.out.println("Keliling Lingkaran :" + kel);
}
}

2. Menghitung Derajat 


import java.util.Scanner;
class derajat
{
public static void main(String args[])
{

Scanner input = new Scanner(System.in);

int clfahry;
double floktavian, rloke;

System.out.print("Masukan Nilai Derajat Celcius : ");
clfahry = input.nextInt();

rloke = clfahry * 0.8;
floktavian = rloke + 32;

System.out.println("Derajat Fahrenheit :" + floktavian);
System.out.println("Derajat Reamor    :" + rloke);
}
}
