Looking at a string ...

Hey guys - quick question.

I'm writing a little program just for the fun of it, and to start off I'm having the user enter a string - the string will be inputted in the same format but there will be different numbers in the spots.

I need to go through the string and when it comes upon the group of characters that will always match, I need it to pull the variable out. For example, the string will always have the format "This is x and this is y" - but x and y will change. So when it goes through the string and comes upon "and" it should go back and grab the x value.

Any ideas?

Thanks

If you mean the input will be like:

This is 2 and this is 2564
This is 42 and this is 12

then you can use the Pattern and Matcher classes.

Look up 'Regular Expressions'. This is a good place to start:
