    Default syntax question

    lets say i have a string object...this string object holds 3 separate "future" int data types...which i can easily "tokenize" and then convert to an int for a variable to hold.

    ex. "25 5 500"

    question is...how can i access say the int of 500 from this string object in one statement so I am able to compare it to another int variable?

    String line = "25  5  500";
    new String(line);  //string object created 
     
    st = new StringTokenizer(line, " ");
                while(st.hasMoreTokens()){
                    String arr = st.nextToken();
                    String p = st.nextToken();
                    String cpu = st.nextToken();
                    int arrival = Integer.parseInt(arr.trim());
                    int pid = Integer.parseInt(p.trim());
                    int cputime = Integer.parseInt(cpu.trim());       
                }

    arrival = 25
    pid = 5
    cputime = 500

    Not sure I understand the question...you are accessing the 3rd int value in the 'cputime' variable and can just use the == to compare to another int
