Hi James,
Yes, you can use split in this case but I think that you are mixing
between splitting name / name and first name / last name -- that the
reason you are not getting an output.
Here is my solution - you will see an output but for three members only
(try to workout from 3 to 6 members):
public static void main(String[] args) {
//Declare counter and number of names to be entered (members)
int i=0;
int members=3;
String[] names = new String[members];
//Input name
for (members = 0; members < 3; members++) {
names[members] = JOptionPane.showInputDialog("Please enter
the family member name");
}
// if(i<members){//i++;
// names[i]=JOptionPane.showInputDialog("What is your
name?");
// i++;
// }
//else{
// Get the first name from a name string using split()
instance(non-static) method
String[] nameArray0 = names[0].split(" ");
String[] nameArray1 = names[1].split(" ");
String[] nameArray2 = names[2].split(" ");
// String[] nameArrayForPerson2 = person2NameInstance.split
(" ");
// Get the lengths of strings using length() instance (non
static) method
int lengthFirstName0 = nameArray0[0].length();
int lengthFirstName1 = nameArray1[0].length();
int lengthFirstName2 = nameArray2[0].length();
// Compare the lengths of the first names between person1 and
person2
if (lengthFirstName0 > lengthFirstName1){
System.out.println(nameArray0[0] +
" has longer first name than " +
nameArray1[0]);
}
if(lengthFirstName1>lengthFirstName2){
System.out.println(nameArray1[0]+" has longer first name
than "+nameArray2[0]);}
else{System.out.println(nameArray2[0]+" has the longest
first name.");}
}
// }
}
I hope it helps,
Moria.

Subject: [java programming] LAB1036 - not getting any output
Hi,
Bit late joining the course so trying to catch up!
I'm on the JavaArray homework from LAB-1036 but I'm having some
problems. It looks ok to me, but when I run I get asked my name and
then it finished. No error messages though. Have I used split right?
And is there anyway to keep all the split names in a single array?
e.g. [first][last]
Cheers,
James
