overloaddemo.java

我在学习JAVA的讲义

import java.awt.Graphics;
import java.applet.Applet;

class IntSort
{   public String sort(int a,int b)
    {   if(a>b)
            return a+" "+b;
        else
            return b+" "+a;
    }

    public String sort(int a,int b,int c)
    {   int swap;
        if(a<b)
        {   swap=a;
            a=b;
            b=swap;
        }
        if(a<c)
        {   swap=a;
            a=c;
            c=swap;
        }
        if(b<c)
        {   swap=b;
            b=c;
            c=swap;
        }
        return a+" "+b+" "+c;
    }
}
public class OverloadDemo extends Applet
{   IntSort s=new IntSort( );
    public void paint(Graphics g)
    {   int a=12,b=34,c=56;
        g.drawString("两个数的排列结果是:"+s.sort(a,b),30,30);
        g.drawString("三个数的排列结果是:"+s.sort(a,b,c),30,60);
    }
}
