Get and Set methods

[garfield1]

Hi
I am trying to create a program that finds the area of a triangle. I can easily find the area of the triangle but the problem is that I have been said to use the set and get method to calculate the area. I have no idea of how to use get and set method with an object. Any help or advice. I have posted my code below.

public class TriObj {
	public void runIt()
	{
		Scanner in = new Scanner (System.in);
		int b;
		int h;
		int a;
		System.out.println("Enter b of triange: ");
		b=in.nextInt();
		System.out.println("Enter h of triange: ");
		h=in.nextInt();
		a=(b*h/2);
		System.out.println("The a of the triangle is: "+ a);
	}
}

Hello
I think it would be great if you declare base, height and area outside the method. I have created a sample example see if it help's you.

public void sb(int b) {
    this.b=b;
}

public int ga() {
    return area;
}

And your constructor should look somewhat like this

public Trio(int b, int height) {
    this.b=b;
    this.height=height;
}

Hi
If you need then you can also use gh(), gb() and recomp(x,x) methods. I have shown it in the code below. Check it out.

public int gh(){
     return height;
}
public int gb(){
     return b;
}
public void reCompute(int height, int b){
     this.b = b;
     this.height = height;
     this.area = b*height/2;
}

Hope this may increase your options. Enjoy programming

Hi
Yes it is correct you can do this as above posted but then you need to do the re-computation in those methods. Or you can change your code like this.

public int ga(){
     return b*height/2;
}
