Thread: Use a Method in Java to find the Last name of any given name

I need to use a method to find out the last name of any given name - meaning given any full name as a parameter the method should return the last name.

Here is the code that I have written but which will not compile. Need help! Thanks in advance


class LastName {
public static void main(String[] args) {
getlastName(" ");
System.out.println();
}

public static String getlastName(String lastName) {

System.out.println("Enter your full name: ");

int firstSpace = fullName.indexOf(" ");
int middleSpace = fullName.middleIndexOf(" ");
lastName = fullName.substring(firstSpace,middleSpace);
return lastName;
}
}
.

which will not compile

... and copy-paste your compiler errors.

given any full name as a parameter the method should return the last name.

What is the format for the full name?
last, first
last first
first last
first middle last
If the full name is in a String and you know what format it is in, the String class has several methods that would be useful: indexOf, substring and split for example.

The format for the full name is First, Middle, Last.

Thanks in advance.

Best Regards,

Look at the different versions of the indexOf method to scan to the second or last space.

getlastName(" "); is returning a String and where in your program you are trying to get the returned value?
If it's not even compiling, copy & paste the full description of errors here.
