java Syntax (Toggle Plain Text)

public class Shape {
int height;
int width;
public Shape() {
height = 1;
width = 2;
}
}
 
public class Triangle extends Shape {
double area;
public Triangle() {
super(); // this means height = 1 and width = 2
area = height * width / 2.0;
}
}

public class Shape { int height; int width; public Shape() { height = 1; width = 2; } } public class Triangle extends Shape { double area; public Triangle() { super(); // this means height = 1 and width = 2 area = height * width / 2.0; } }

In this example, Circle is the child class of Shape and it's constructor calls super as its first instruction and then extends it by doing something after.

Hope this helps,

You could then add things such as area, volume and other attributes from that base.

Could you also change one of the original attributes? Say if I wanted to call Super, but make the newest object have a height of 2.
