    Question String indexOf

    hi...I want to find the index of "{" bracket in a string but it is showing -1 always why?
    here is my code:
    File file1 = new File("prob.txt");
    //StringBuffer contents = new StringBuffer();
    BufferedReader reader = null;
    String text=null;
    try
    {
    reader = new BufferedReader(new FileReader(file1));


    while ((text = reader.readLine()) != null) {
    String []splits1 = text.split(" \\s+." );
    for(int j=0; j< splits1.length ;j++){

    if(splits1[j].length() > 0 && splits1[j].charAt(0) == '1'&& splits1[j].charAt(1) == '0')
    {
    int h=splits1[j].indexOf('{');
    System.out.println(h);
    System.out.println(splits1[j]);
    System.out.println("rashi");
    }


    }
    }
    }

    MY string is:
    10 3.94 4.87 7.27 9.34 11.78 13.44 15.99 (18.31) [23.21] .

    That doesn't have any curly braces in it. In this case indexOf() returns -1.

    Of course, I don't know what he expected the index of a non-existant character to be.
