as the title says i'm heaving problem while iterating arraylist of arrays. Here is my definition: public static ArrayList<JTextArea[]> ta;
here is how i read value from it:
Iterator<JTextArea[]> i = Interface.ta.iterator();
while(i.hasNext())
{
JTextArea[] t = (JTextArea[]) i.next();
ret += t[0].getText() + ", ";
}
The JTextArea array is always an array of four elements and in this while I have to read the text of the firstone. The problem is simple, the "next()" method gives me every JTextArea object, not the complete array made of 4 JTextArea s.
Any way to get the Next() method pick all the array?
Thanks in advance
Use For Each
instead of Iterator
for (JTextArea[] jTextAreaArray : ta) {
// Use jTextAreaArray to do your process.
}
It is very simple to use rather than Iterator
To get Individual Objects use.
for (JTextArea[] jTextAreaArray : ta) {
for(JTextArea jTextArea : jTextAreaArray ){
// Do your Process with Individual jTextArea.
}
}
You should be able to reference t[1], t[2], t[3] for the other 3 in the t array, so your codes should be:
ArrayList<JTextArea[]> ta=null;
// setup ta here;
String ret = "";
Iterator<JTextArea[]> i = ta.iterator();
while (i.hasNext()) {
JTextArea[] t = i.next();
ret += t[0].getText() + ", ";
ret += t[1].getText() + ", ";
ret += t[2].getText() + ", ";
ret += t[3].getText() + ", ";
// or
for (int x=0; x<t.length; x++) {
ret += t[x].getText() + ", ";
}
}
