Question

Please find my example code below:

    String[] tempCrfFC = crfFC;                //crfFC is a String[] itself
    for(int i = 0; i < crfFC.length; i++) {
        String[] crfTok = tempCrfFC[i].split("\\s");
        if(crfTok.length == 40) {
            if(crfTok[39].split("/")[0].equals("O")) {
                Double v = Double.parseDouble(crfTok[39].split("/")[1]);
                if (v <= d && (i == 0 || prevTagged != i-1)) {
                    tempCrfFC[i].split("\\s")[39] = "A";    //<-------
                    System.out.println("val: "+tempCrfFC[i].split("\\s")[39]);
                    System.out.println("tempCrfFC: "+tempCrfFC[i]);
                    prevTagged = i;
                }
             }
        }
    }

Example of a tempCrfFC line:

The  T       Th      The     null    e       he      The     null   Aaa     Aa    1       1       1       0       0       0       0       0       0       0       0       0       0       0       0       0       0       0       0       O       B       O       B       O       0       DT      O       O/0.892667

At the line marked with “<—–” I wish to reassign the existing value to a new value “A”. However, on printing the output, the observation is that the value at that index (39) remains unchanged. Could someone help me resolve this?

Thank you.

Try

String[] tempCrfFC = crfFC;                //crfFC is a String[] itself
for(int i = 0; i < crfFC.length; i++) {
    String[] crfTok = tempCrfFC[i].split("\\s");
    if(crfTok.length == 40) {
        String[] parts = crfTok[39].split("/");
        if (parts[0].equals("O")) {
            Double v = Double.parseDouble(parts[1]);
            if (v <= d && (i == 0 || prevTagged != i-1)) {
                cfTok[39] = "A";    //<-------
                System.out.println("val: " + cfTok[39]);
                tempCrfFC[i] = join(cfTok);
                System.out.println("tempCrfFC: " + tempCrfFC[i]);
                prevTagged = i;
            }
         }
    }
}

where join is a method that joins your string back from an array.
