---------- BEGIN SOURCE ----------
class Bugette2
{

public static void main(String[]args)
{
        Object[]obj={123,123l,1.2f,1.2d};
        String[]str={"123","123l","1.2f","1.2d"};
        Class[]cl={Integer.class,Long.class,Float.class,Double.class};
        for(Object o:obj)prln(o,o.getClass());
        try{int i=Integer.parseInt("123");prln(i);}catch(Exception e){prln(e);}
        try{long l=Long.parseLong("123l");prln(l);}catch(Exception e){prln(e);}
        try{float f=Float.parseFloat("1.2f");prln(f);}catch(Exception e){prln(e);}
        try{double d=Double.parseDouble("1.2d");prln(d);}catch(Exception e){prln(e);}
}

static void prln(Object...s)
{
        String r="";
        for(Object o:s)r+=" "+o;
        System.out.println(r);
}
}
