Java Strings


Let's hypothetically say you have a simple string, ie "The.Dog.Ran."
and you ONLY want to get rid of the LAST period without altering the others. How would you do that easily? Preferably without the use of arrays. So basically the end result would be to display "The.Dog.Ran"

Sure thing mate. You've to use .length() which returns the size of a string and .substring(start, stop) to read a string from the beginning till the end. Here is a working example:

Code:
public class Testing{
	public static void main (String[] arguments){
		String ie = "The.Dog.Ran.";

		System.out.println(ie.substring(0, ie.length()-1));
	}
}
Regards!

String s = "The.dog.ran."
int idx = s.lastIndexOf(".");
String result = s.substring(0,idx); // this is now "The.dog.ran"
