    Default Try- catch block + return + IO package


    I have a doubt in usage of return stmt in try-catch block. I have a function in which i read a file and that i stored in a String array. All this part will be written in try-catch block. I would like return that string array. Where I have to put this return stmt.

    public int[] readDataFromAFile()
    String tkn[]=null;
    BufferedReader br = new BufferedReader(new FileReader("PrintOutput.txt"));
    String line;
    tkn =line.split(",");
    for(int i=0; i<tkn.length;i++)
    catch(Exception e)
    System.out.println("Exception: " + e);
    return tkn;

    By running this code it is showing 2 errors.
    1st error at At catch block.
    2nd is at return stmt.

    Invalid expression statement.
    error: '{' expected.
    return tkn;

    Syntax error is a different issue, but what exactly are you supposed to return from this method? Because your method signature says return type is array of int, however what you are returning i.e. tkn is a array of String.
