Parse Array of Objects - string delimiter java

[Pedro Rocha]

How can I parse an object from an array of objects
into a comma delimitted String.

ex:
definition
Cat (String cName, StringcDesc , String cAge)

Cat [] arrayOfCatObjects;

Say I want all the Cat objects into a String (comma delimitted)

something like:
"cat1,stray,8,cat2,bluecat,3"

Any ideas?

thanks

---------------not tested ---------------
String catlist;

for (int j = 0; j < Cat.length; j++)
{
catlist += Cat[j].cName;
}

oops forgot the comma
---------------still not tested ---------------
String catlist;

for (int j = 0; j < Cat.length; j++)
{
if(j!=0) catlist += ",";
catlist += Cat[j].cName;
}

Pedro is asking fir a String (comma delimitted) including the name, desc,
and age.
So the following does not work.

---------------still not tested ---------------
String catlist;

for (int j = 0; j < Cat.length; j++)
{
if(j!=0) catlist += ",";
catlist += Cat[j].cName;
}

try:

String catlist;

for (int j = 0; j < Cat.length; j++)
{
if(j!=0) catlist += ",";
catlist += Cat[j].cName +","+ Cat[j].cDesc +","+ cat[j].cAge;
}

String[] knownNames {"fluffy","unknown","scratch"}
String[] breed {"tabby","siamese","calico"}
String[] ages {"8", "10","12"}


public String toString

for ()

StringBuffer sb = new StringBuffer();

sb.append(knownNames)
sb.append(breed)
sb.append(ages)

return sb.toString()

seems to work,
all suggestions are valid for me
thank you !

Hi !
It could also be beautiful to override Cat.toString, and use
Collection.toString()...

i.e.
for Cat
String toString()
{
return new
StringBuffer(cName).append(',').append(cDesc).append(',').append(cAge)
}

then
// Produces [ cat1, desc1, age1, cat2, desc2, age2 ]
String result_l = Arrays.asList(arrayOfCatObjects).toString();
// Remove 1st and last character [ & ]
result_l = result_l.substring(1, result_l.length-1);

In this case it would be unnesscary to explicitly use StringBuffer, the
following statement is just as effecient and a lot more readable:
return cName + ',' + cDesc + ',' + cAge;
