Program Sederhana Java (operator logika)

1.  Program Mencari Nilai Rata - rata

public class RataRata {

      /**

       * @param args

       */

      public static void main(String[] args) {

            // TODO Auto-generated method stub

           

            int number1 = 10;

            int number2 = 20;

            int number3 = 45;

            System.out.println("Number 1 = "+number1);

            System.out.println("Number 2 = "+number2);

            System.out.println("Number 3 = "+number3);

            int rata = (number1+number2+number3)/3;

            System.out.print("Rata-rata = "+rata);

      }

}

Outputnya :

2.  Program Mencari Nilai Terbesar

public class NilaiTerbesar {

      /**

       * @param args

       */

      public static void main(String[] args) {

            // TODO Auto-generated method stub

           

            int number1 = 10;

            int number2 = 23;

            int number3 = 5;

            System.out.println("Number 1 = "+number1);

            System.out.println("Number 2 = "+number2);

            System.out.println("Number 3 = "+number3);

            int terbesar = 0;

            terbesar = (number1>=number2)?number1:number2;

            terbesar = (number3>=terbesar)?number3:terbesar;

            System.out.println("Nilai tertingginya adalah angka = "+terbesar);

      }

}

Outputnya :

3.  Program Menggunakan BufferedReader

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class InputBufferedReader {

      /**

       * @param args

       */

      public static void main(String[] args) {

            // TODO Auto-generated method stub

           

            BufferedReader data1 = new BufferedReader(new InputStreamReader(System.in));

            String kata1 = "";

            System.out.print("Enter word 1 : ");

            try {

                  kata1 = data1.readLine();

            } catch (IOException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

            String kata2 = "";

            System.out.print("Enter word 2 : ");

            try {

                  kata2 = data1.readLine();

            } catch (IOException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

            String kata3 = "";

            System.out.print("Enter word 3 : ");

            try {

                  kata3 = data1.readLine();

            } catch (IOException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

            System.out.print(kata1+" "+kata2+" "+kata3);

      }

}

Outputnya :
