Hi,
I have a java program that has a string.The string contains different numers(multi digit) and characters. I want to extract these numbers into different variables.
for eg. if the string is c 32 34.
Then I want to extract c, 32 & 34.
Please help me . Thanks in advance.

Pick off the fields with StringTokenizer.
To test if a field is a number, or whatever, you can use Integer.parseInt() inside a try/catch statement.

If you're in JDK 5 play with Scanner. By default it will pull tokens off a string delimited by spaces (just what you need) and convert them to various types if possible.
