how to separate integer numbers from a string?

I have a string 

String exp = "7 to 10";

now I am keeping a condition that 

if (exp.contains("to"))
{
    // here I want to fetch the integers 7 and 10
}

How to separate 7 and 10 from the string 7 to 10 (parsed as Integer).

By using a delimiter I can obviously do it but I want to know how to do it this way?

Try following code it would work for any string.

String test="7 to 10";
String tok[]=test.split(" (\\w+) ");
for(String i:tok){
    System.out.println(i);
}

Output :

7
10

Here is the code,

import java.io.*;

public class test
{
     public static void main(String[] args) {

        String input="7 to 10";//pass any input here that contains delimeter "to"
        String[] ans=input.split("to");

        for(String result:ans) {
        System.out.println(result.trim());
        }
    }
}

Please check and let me know if it works fine for you.

Using split:

    if (exp.contains(" to ")) {
        String[] numbers = exp.split(" to ");
        // convert string to numbers  
    }

Using regex:

    Matcher mat = Pattern.compile("(\\d+) to (\\d+)").matcher(exp);
    if (mat.find()) {
        String first = mat.group(1);
        String second = mat.group(2);
        // convert string to numbers
    }
