Java

______________________________________________________

Dag minecraft

public class voorbeeld1 {

public static void main(String[] args) {

System.out.println("Hello minecraft");

}

Maak een file, voorbeeld1.java
Voeg de code toe en bewaar
command prompt / terminal
Compileren (vertalen) ==> javac voorbeeld1.java
Uitvoeren ==> java voorbeeld1

Merk op

hoofdletters, kleine letters
gebruik van ;
verder

Alles steekt in een "class"
Een class heeft methods
main is een "method"
System.out... is een statement - die moeten eindigen met ;

______________________________________________________

Dag wie

public class voorbeeld2 {

public static void main(String[] args) {

System.out.println("Hello " + args[0]);

}

Merk op

String[] args - type + naam
String concatenatie via +

______________________________________________________

Variabelen

public class voorbeeld3 {
public static void main(String[] args) {
int getal1 = 124;

int getal2 = 44438;

int som = getal1 + getal2;

System.out.println(getal1 + "+" + getal2 + "=" + som );

}
}

Merk op

Variabelen hebben een naam
Variabelen hebben een type : (int, String, boolean, float)

______________________________________________________

Condities

public class voorbeeld4 {

public static void main(String[] args) {

int getal = 1240;

if ( getal == 124 ) {

System.out.println("Honderdvierentwintig");

} else {

System.out.println("Geen honderdvierentwintig");

}

Merk op

Gebruik == om te vergelijken (getallen)

______________________________________________________

Loops (lussen)

public class voorbeeld5 {

public static void main(String[] args) {

int aantalKeren = 100;

for(int teller=1;teller <= aantalKeren;teller++) {

System.out.println("Teller is : " + teller);

}

gelijkaardig

public class Voorbeeld6 {

public static void main(String[] args) {

int teller = 100;

while (teller >= 1 ) {

System.out.println("Teller is : " + teller);

teller--;

}

Merk op

variabele++ => verhoogt waarde van de varariabele met 1 (zelfde als variable = variable + 1)
variabele-- => vermindert waarde van de varariabele met 1 (zelfde als variable = variable - 1)

______________________________________________________

Classes

rekenmachine.java

public class rekenmachine {

int getal1;

int getal2;

public rekenmachine(int g1, int g2) {

getal1 = g1;

getal2 = g2;

}

public int plus() {

return getal1 + getal2;

}

public int maal() {

return getal1 * getal2;

public static int plus2(int waarde1, int waarde2) {

int getal2 = 44438;

Rekenmachine teller = new rekenmachine(getal1,getal2);

System.out.println("maal=" + teller.maal() );

int som2 = rekenmachine.plus2(100,200);

System.out.println("som2=" + som2 );

}

Merk op

new naam van class -> nieuw 'object' met als 'type' de class
instance method tov static method

object.method : instance method
class.method : static/class method
