期末心得

本學期修了許老師的JAVA課程，剛開始感覺很簡單也覺得很有趣。老師的教學方式也是很好的方法。從錯誤中學習，可以讓同樣的錯誤不會再犯錯!

JAVA 作業4/9

class calcArea{
public static void main(String[] args)
{
int a,b;
double triArea,rectArea;
String s1,s2;
s1=args[0];
s2=args[1];

Triangle calcTri = new Triangle();
triArea = calcTri.calc(s1,s2);

Rectangle calcRect = new Rectangle();
rectArea = calcRect.calc(s1,s2);

System.out.println("長 = "+s1);
System.out.println("高 = "+s2);
System.out.println("三角形面積 = "+triArea);
System.out.println("長方形面積 = "+rectArea);
}}

class Triangle{
Triangle()
{
//System.out.println("三角形面積");
}

static int calc(String s1, String s2){
int x,y,z;
x = Integer.parseInt(s1);
y = Integer.parseInt(s2);
z = x * y /2;
return z;
}}

class Rectangle{
Rectangle()
{
//System.out.println("長方形面積");
}

static int calc(String s1, String s2)
{
int x,y,z;
x = Integer.parseInt(s1);
y = Integer.parseInt(s2);
z = x * y;
return z;
}}

JAVA 作業

class add

int z=0;
x=args[0];
y=args[1];
z=Integer.parseInt(args[0])+Integer.parseInt(args[1]);
System.out.println(x);
System.out.println(y);
