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
