java的調試

『壹』 java調試

第一問：

publicclassPoint
{
intx,y;
	floata,b;
	staticintz;

	voidsetValue(intm,intn)
	{
		this.x=m;
		this.y=n;
	}

	voidsetValue(floata,floatb)
	{
		this.a=a;
		this.b=b;
	}

	staticvoidoutput()
	{
		Pointpoint=newPoint();
		System.out.println("x="+point.x+",y="+point.y+",a="+point.a+",b="+point.b+",z="+Point.z);
	}
}

第二問：

publicPoint()
{
	super();
}

publicPoint(intz1,intz2,floatz3,floatz4)
{
	this.x=z1;
	this.y=z2;
	this.a=z3;
	this.b=z4;
}

第三問：

publicstaticvoidmain(String[]args)
{
	Pointpt1=newPoint();
	pt1.setValue(1,2);
	pt1.setValue(3,4);

	Pointpt2=newPoint();
	pt2.setValue(5,6);
	pt2.setValue(7,8);
}

第四問：

Pointpt3=newPoint(9,10,11,12);

第五問：

System.out.println("x="+pt1.x+",y="+pt1.y+",a="+pt1.a+",b="+pt1.b);
System.out.println("x="+pt2.x+",y="+pt2.y+",a="+pt2.a+",b="+pt2.b);

第六問：

System.out.println("pt1.z="+pt1.z);
System.out.println("pt2.z="+pt2.z);
System.out.println("pt3.z="+pt3.z);
pt1.output();
pt2.output();
pt3.output();
System.out.println("Point.z="+Point.z);
Point.output();
output();

希望可以幫到你。
