about awt.I have problem to print out numbers next to ....
Hi to everyone,
I am new in java programming and new in this forum.So sorry if i do something wrong.
About awt.I have problem to print out numbers next to a box.It is about a thermometer and i would like to put next to this a column of numbers.for example spmethinf like:
100
80
60
40
20
I know it is only a for loop but i can't do it because i am confused with the methods.I use drawString("",int x ,int y). BY the way how can i convert integer to string?
thanks

String str= args[0] ;
TempWindow myTemp = new TempWindow(str);
myTemp.show();
}
}
this is my code.is not working well.if you my comments you can understnd!
