Berikut adalah beberapa codingan mengenai program sederhana dalam Java :

Menghitung Nilai Akhir Sekolah

import java.util.Scanner;
public class NilaiAkhir {
static double na,nUTS,nUAS,nTugas,Nilai;
static Scanner s;
public static void main(String[] args){
s = new Scanner(System.in);

System.out.println("Masukkan Nilai UAS :");
nUAS = s.nextInt();

System.out.println("Masukkan Nilai UTS :");
nUTS = s.nextInt();
System.out.println("Masukkan Nilai Tugas :");
nTugas = s.nextInt();
na = (nUAS*0.35)+(nUTS*0.3)+(nTugas*0.35);

System.out.println("Nilai Akhir = " +String.format("%.2f",na));
Nilai=na;
System.out.println("Nilai Huruf = " +getHuruf(Nilai));
}
static char getHuruf(double Nilai){
char huruf;
if (NilaiAkhir.Nilai<50)
huruf='E';
else if (NilaiAkhir.Nilai<60)
huruf='D';
else if (NilaiAkhir.Nilai<70)
huruf='C';
else if(NilaiAkhir.Nilai<85)
huruf='B';
else
huruf='A';
return huruf;
}
}

Program Hitung Luas dengan Case 

import java.util.Scanner;
public class ProgramHL{
double panjang,luas,jari,lebar,alas,tinggi;
double phi = 3.14;
Scanner masuk = new Scanner(System.in);
public static void main(String[]args){

object.program();
}
public void program(){

System.out.println("2. Segitiga");
System.out.println("3. Lingkaran");
System.out.println("4. Keluar");
System.out.println("=========================");
System.out.println("Masukkan Pilihan :");
int pilihan = this.masuk.nextInt();

switch(pilihan){
case 1: persegipanjang();
break;
case 2: segitiga();
break;
case 3: lingkaran();
break;
case 4: keluar();
break;
default:System.out.println("Pilihan Yang Anda Masukkan Salah");
program();
}
}
void persegipanjang(){
System.out.println("Masukkan Lebar :");

tinggi = masuk.nextInt();

luas = (alas*tinggi)/2;

System.out.println("("+alas+"*"+tinggi+")/2= "+luas);
}
void lingkaran(){
System.out.println("Masukkan Jari-jari Lingkara :");
jari = masuk.nextInt();

luas = (jari*jari)*phi;

System.out.println("("+jari+"*"+jari+")*phi = "+luas);
}
void keluar(){
System.out.println("Terima Kasih");
System.exit(4);
}
}
If

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

System.out.print("Masukkan nilai:");
nilai = s.nextInt();

if(nilai>70)
System.out.println("Lulus");
else
System.out.println("Gagal");
}
}
If Else

import java.util.Scanner;
