String to int & back again

Thread view:

fb - 21 Jan 2006 02:18 GMT

Hello. I have the following code:

float num = 205.0f;
String myString = "0";
for(int i=0;i<=5;i++){
g2D.drawString(myString,70.0f,num);
num-=20.0f;
myString+=10;
}

I am looking to increase the value of myString by 10. However, since it
is a string I can't really increment it...(Can I?), So I was wondering
If there is a simple way to achieve this. (Or any way at all really).

ttyl.

Well Strings are immutable so you can can't them. However, you can
change what String the String reference myString refers to.

You can do something like this:

int myNum = 0;
String myString = "" + myNum;

// do things and increment myNum

myString = "" + myNum;

Alternatively you can convert from String to int by:
int myInt = Integer.parseInt(myString);

see http://mindprod.com/applet/converter.html

for String > int and int > String.

If you find yourself doing this often, you might decide to keep the
int value around and only generate the String when it comes time to
play.

This thinking goes way back to COBOL COMPUTATIONAL-n variables.

How about looking at it the other way around..

float num = 205.0f;
int myInt = 0;

for(int i=0;i<=5;i++)
{
g2D.drawString(Integer.toString(myInt),70.0f,num);
num-=20.0f;
myInt+=10;
}

Thanks in Advance...

If you need to increment myString so often, then maybe you should consider
using an int in the first place - and cast it to a string when you need it.

Try

float num = 205.0f;
int myInt = 0;
for(int i=0;i<=5;i++){
g2D.drawString("" + myInt,70.0f,num);
num-=20.0f;
myInt+=10;
}
