Question

I’d like to get a string from my ArrayList, but it contains lines from my input fole. How do I split them correctly to have all the elements?

My program looks like this:

private static ArrayList<String> lista;

static void fileReading() {
    inp = new LineNumberReader(new BufferedReader(new InputStreamReader(new FileInputStream(inFileNev), "ISO8859-1")));

    String sor;
    while ((sor = inp.readLine()) != null) {

    lista.add(sor);
    lista.add(System.getProperty("line.separator"));   
}

In another method how do I get this lists only one string and not the line?

EDIT:

Vineet Verma your code is great, but it gets me a great string, and I need to know the indexes of the strings within this, replace them later, and I can’t get it done with only one string.

It’s still not working, if I use this:

    String[] temp=null;
for(String s : lista) {
   temp = s.split("\\W+"); 
} 

System.out.println(temp);

I get: [Ljava.lang.String;@6ef53890

Wihtin the for I get many : [Ljava.lang.String;@6ef53890

If I use this:

   String str ="" ;
    for(int i=0; i<lista.size(); i++){
     str+=lista.get(i)+" ";

  String[] temp = new String[str.length()];
  for(int i=0; i < str.length(); i++) {
       temp[i]=str.valueOf(i);
       System.out.println(temp[i]);         
  }

I get only numbers, and can’t figure out how to get the string from str.

Answer 1

Use this code for your problem:

in the other method

public String convertToString(ArrayList<String> al)
{
String str ="" ;
for(int i=0; i<al.size;i++){str+=al.get(i)+" ";}
return str;
}

If i understand your query correctly then this is the solution
