Question

Here i have this type of String and i want to split this string in to every elements and want to make one arraylist(integer) or one integer array for numbers.

I have String like this for a example : 123|00,124|01,125|00,126|01

I want to first seprate all elements in one list which contains

123|00
124|01
125|00
126|01

And after i want to make one integer array list or integer array which have only

123
124
125
126

Please any body can suggest me how can i do this

Thanks

Code:

            List<Integer> numberList = new ArrayList<Integer>();
        HashMap<Integer, Integer> statusMap = new HashMap<Integer, Integer>();
        for (String tripnumber : tripNumbers) {

            int number = Integer.parseInt(tripnumber.split("[|]")[0]);
            Logger.d(TAG, "Trip number in Status Message = "+number);

            int flag = Integer.parseInt(tripnumber.split("[|]")[1]);
            Logger.d(TAG, "TM flag = "+flag);

            if (number > 0) {
                statusMap.put(number, flag);
                numberList.add(number);
            }
        }

Answer 1

String str = "123|00,124|01,125|00,126|01";

// Split on `|` or `,` and then take every alternate element.
String[] tokens = str.split("[|,]");

List<Integer> intList = new ArrayList<Integer>();    
for (int i = 0; i < tokens.length; i = i + 2) {
    intList.add(Integer.parseInt(tokens[i]));
}

UPDATE: –

If you have inconsistent values separated by | and ,, then you need to split on them separately: –

String str = "123|00,125|,126|01,|,";
String[] tokens = str.split(",");
Map<Integer, String> flagMap = new HashMap<Integer, String>();

    for (String token: tokens) {
        String[] arr = token.split("[|]");

        if (arr.length == 0) {
            continue;
        }
        if (arr[0].length() > 1) {
            if (arr.length == 2) {
                flagMap.put(Integer.parseInt(arr[0]), arr[1]);
            } else {
                flagMap.put(Integer.parseInt(arr[0]), "");
            }
        }
    }

    System.out.println(flagMap);

OUTPUT: –

{126=01, 125=, 123=00}
