StellarConstructors, parameters, and methods
Let’s say we want to make a program that can keep track of a point’s position with its public fields x, y, and z. Below is an example of how to track the point with directly accessing public fields:
public class Main {
public static void main(String[] args) {
Point point1 = new Point();
point1.x = -4.6;
point1.y = 7.8;
point1.z = -1.5;
//setting all of the coordinates on separate lines is verbose! If only there was a better way…
System.out.println("The point is at ("+point1.x+", "+point1.y+", "+point1.z+")");
}
}Output
The point is at (-4.6, 7.8, 1.5)
public class Point {
public double x, y, z;
}
