Trying to create a meaningful data structure in Java, got problem.

Hi there,

I tried to create a meaningful data structure in JavaScript, and I didn't
seem to be able to find the right syntax or perhaps this is not supported:

The only thing I can come up with is not nice but it's working:

EX:

sqldata = new Array(1..n);

or

MaxElement = 12;

sqldata = new Array(Array(1..n1), Array(1..n2), MaxElement) ;

So to subscribe/view MaxElement, I have to do something like this:

sqldata[2]

Instead of:
sqldata.MaxElement


Using enum is not accepted in Javascript. Any one knows a different way I
can try? Using a Class didn't seem to work neither.


Thanks for your suggestion.

Don't know if you have a solution yet...

From my experience using a class is the way to define a data structure.

Here is a simple example (nothing fancy for sure - certainly needs
improvement especially managing the vector declaration) that creates 3 data
structures and adds them to a vector. Then it searches the vector for a
match.

import java.util.*;

/**
* vec.java
*/
public class vec {

Vector x = new Vector();

public vec(){
//add some data structures to the vector
abc aBC = new abc();
aBC.name = "Me";
aBC.place = "Here";
x.add(aBC);
abc xYZ = new abc();
xYZ.name = "Too Much";
xYZ.place = "Much";
x.add(xYZ);
abc dEF = new abc();
dEF.name = "Far Out";
dEF.place = "There";
x.add(dEF);

//clean up a little
aBC = null;
xYZ = null;
dEF = null;

/* get a value from the vector...*/
abc z = getItem("Me");
if (z != null) {
System.out.println(z.name + " " + z.place);
} else {
System.out.println("No Match");
}
z = null;

/* get a value from the vector - doesn't exist!!...*/
abc y = getItem("Mee");
if (y != null){
System.out.println(z.name + " " + z.place);
}else{
System.out.println("No Match");
}
}

public abc getItem(String c){
int i;
abc d = null;

for (i = 0; i < x.size();i++){
d = (abc)x.get(i);
if (d.name.equals(c)){
break;
}
}

if (i == x.size()) {
//didn't find match
d = null; // d would have value of last element of vector so
null it
}
return d;
}

// The data structure
private class abc {

String name = new String();
String place = new String();

}


public static void main(String[] args) {

vec y = new vec();
}
}
