For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Java Interitance Example

This is the first example of Java Inheritance shown on our recent Java course - the second example is here

Anitest.java


public class Anitest {

public static void main(String [] args) {

Farm ermintrude = new Farm("Cow",100,20);
Farm cocky = new Farm("Cockerel",4,2,2);
Pet belle = new Pet("Cat",5,300);

int ew = ermintrude.getweight();
int ev = ermintrude.getvalue();
String et = ermintrude.getbreed();
int el = ermintrude.getlegs();
System.out.println(et + " which weighs " + ew +
" worth " + ev + " legs: "+el);

ew = cocky.getweight();
ev = cocky.getvalue();
et = cocky.getbreed();
el = cocky.getlegs();
System.out.println(et + " which weighs " + ew +
" worth " + ev + " legs: "+el);

ew = belle.getweight();
ev = belle.getvalue();
et = belle.getbreed();
el = belle.getlegs();
System.out.println(et + " which weighs " + ew +
" worth " + ev + " legs: "+el);
}}

Farm.java


public class Farm extends Animal {
int vpk;

public Farm (String breed, int weight, int vpk) {
super(breed, weight);
this.vpk = vpk;
}

public Farm (String breed, int weight, int vpk, int legs) {
super(breed, weight, legs);
this.vpk = vpk;
}

public int getvalue() {
return vpk * weight;
}
}

Pet.java


public class Pet extends Animal {
int v;

public Pet (String breed, int weight, int v) {
super(breed, weight);
this.v = v;
}

public int getvalue() {
return v;
}
}

Animal.java


public class Animal {
String breed;
int weight;
int legs;

public Animal(String breed, int weight) {
this.breed = breed;
this.weight = weight;
this.legs = 4;
}

public Animal(String breed, int weight, int legs) {
this.breed = breed;
this.weight = weight;
this.legs = legs;
}

public String getbreed() {
return breed;
}

public int getweight() {
return weight;
}

public int getlegs() {
return legs;
}
}
