Jorge,
do this and see what happens.
// i am correcting where i feel logic is wrong.
//you are not reading 3 first name so dont make it an array it is regular
string.
//String []firstName = new String [3] ;
String firstName = "";
//now it is not array any more so do this.
// firstName[i] = fullName[i].split(" ");
firstName = fullName[i].split(" ");
Now see what happens.

Hi all,
This been a Month and I'm Stuck with this function named Split.
split Defines
The array of strings computed by splitting this string around matches of the
given regular expression
Return Type is String which is Split
Here is the Code.
******************************************************************************************************************************
public class JavaArrayProject {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String []fullName = new String [3];
// Input for String for FULL NAME
for ( int i=1; i<=3 ; i++ )
{ fullName [i] = JOptionPane.showInputDialog("Please Enter Family
Member "+
i + " First and Last Name ");
}
// Split Function for Extracting First Name
String []firstName = new String [3] ;
for (int i=1 ;i<=3 ; i++ )
firstName[i] = fullName[i].split(" ");
******************************************************************************************************************************
I'm getting a Error in the last line. My logic on that statement is wrong. IDE
gives me "incompatible types" and it says
found : java.lang.string[]
required : java.lang.string
My thoughts are like this..
Full Name = Ravi Nazre
So First Name is Ravi and Last Name is Nazre.
here fullName= Ravi Nazre
if i Use
firstName[ ] = fullName[].split(" ");
It should store First Name
I'm Still wondering what needs to be done here. I want to use Looping Structure
for Scalability.
Please help
Hi all,
I thought a code such that the only fixed (constant) value is the number of
members to enter. It works but I am not sure if I am using correctly the
initialization of the multidimensional array.
In a first step I Initialize the first dimension of the array:
int numberOfMembers = 3;
String[][] arrayOfNames= new String[numberOfMembers][];
In a second stage I ask for the full names of each member (up to
numberOfMembers) and then I initialize the second dimension of the
multidimensional array (and here is where I am not sure if it is valid to do):
for (int i= 0; i< arrayOfNames.length; i++) {
arrayOfNames[i] = new
String(JOptionPane.showInputDialog(String.format("Member #%d, enter your full
name, please", i+1))).split(" ");
}
In a third stage to find the owner of the longest first name:
int longestFirstNameOwner= 0;
int longestFirstNameLength= 0;
for (int i= 0; i<arrayOfNames.length; i++){
if (arrayOfNames[i].length > 0) {
if (arrayOfNames[i][0].length() > longestFirstNameLength){
longestFirstNameLength= arrayOfNames[i][0].length();
longestFirstNameOwner= i;
}
}
}
This code works well. If numberOfMembers where a parameter it will be possible
to find the longest first name of any number of people without modifying this
code. But I still have a doubt, if it is valid to initialize the
miltidimensional array in the way I did.
Thanks averibody
