Java里的matmult类的用法

import java.awt.*;

class Subscript implements DrawingObj {
    private int x, y;

    }

	this.str = str;
	this.sub = sub;
	font = new Font("Courier", Font.PLAIN, 14);
	subfont = new Font("Courier", Font.PLAIN, 10);
    }
	
    public int getX() {
	return x;
    }

    public int getY() {
	return y;
    }

    public void move(int x, int y) {
	this.x = x;

    }

	g.drawString(sub, x + str.length()*9, y + 2);
    }

    public int getRight() {
	return x + str.length()*9 + 7;
    }
}
