Pemograman Java

1.

Sebelum

class Tugas3b

{

public static void main (args)

{

int a = 21;

System.out.println("Nilai a = " + a);

System.out.println("Nilai a++ = " + a++);

System.out.println("Nilai ++a = " + ++a);

System.out.println("Nilai a = " + a);

a+=3)

System.out.println("\n\nNilai a = " + a );

System.out.println("Nilai ++a = " + ++a );

System.out.println("Nilai a++ = " + a++);

System.out.println("Nilai --a = " + --a);

System.out.println("Nilai a = " a--);

}

}

 Analisis :

1.      Kelas yang menjadi program harus memiliki metode public static void main(String[] args)

2.      Penulisan operator aritmatika harus lengkap

Sesudah

class Tugas3b

{

public static void main (String[] args)

{

int a = 21;

System.out.println("Nilai a = " + a);

System.out.println("Nilai a++ = " + a++);

System.out.println("Nilai ++a = " + ++a);

System.out.println("Nilai --a = " + --a);

System.out.println("Nilai a-- = " + a--);

System.out.println("\n\nNilai a = " + a );

System.out.println("Nilai a++ = " + a++ );

System.out.println("Nilai ++a = " + ++a);

System.out.println("Nilai --a = " + --a);

System.out.println("Nilai a-- = " + a--);

}

}

Outputnya

class Tugas3c

{

public static void main (String[] args)

{

int a = 25 ;

System.out.println("Nilai a = " + a);

System.out.println("Nilai a++ = " + a++);

System.out.println("Nilai a = " + ++a);

System.out.println("Nilai a-- = " + a--);

System.out.println("Nilai a = " + a);

a*=2;

System.out.println("\n\nNilai a = " + a);

System.out.println("Nilai a++ = " + a++);

System.out.println("Nilai ++a = " + ++a);

System.out.println("Nilai --a = " + --a);

System.out.println("Nilai a-- = " + a--);

}

}

Outputnya
