コード // class Pt3DCls{ double x, y, z; Pt3DCls(double x){ this(x, x * 10, x * 100); } Pt3DCls(double x, double y){ this(x, y, x * 100); } Pt3DCls(double x, double y, double z){ this.x = x; this.y = y; this.z = z; } } // public class THIS_KEYWARD { public static void main(String[] args) { System.out.println("Start"); // System.out.println("------------------------"); // Pt3DCls p1 = new Pt3DCls(10.0); System.out.println("x = " + p1.x); System.out.println("y = " + p1.y); System.out.println("z = " + p1.z); // System.out.println("------------------------"); System.out.println("End"); } }
結果 Start ------------------------ x = 10.0 y = 100.0 z = 1000.0 ------------------------ End
