    Default Sort String Method

    /*
    So I have this code and I am getting incombatable types, I do not know why I am getting them... Can someone help me figure out why I am getting the error? (See: //Where the problem is)


    The Error I am getting:
    stringSort.java:26: error: incompatible types
    if(myArray[j].compareToIgnoreCase(myArray[i].toString())){
    ^
    required: boolean
    found: int
    */




    import java.util.*;
    import java.io.FileInputStream;
    import java.io.InputStreamReader;
    import java.io.BufferedReader;
    import java.io.FileReader;
    import java.io.FileNotFoundException;

    public class stringSort{
    public static void main(String[] args) throws Exception {

    FileInputStream fstream = new FileInputStream("textfile.txt"); // Open the file
    BufferedReader br = new BufferedReader(new InputStreamReader(fstream)); // allows file to be read

    String strLine;

    int count = Integer.parseInt(br.readLine());
    String[] myArray = new String[count];
    int i = 0;
    while ((strLine = br.readLine()) != null){ //Read File Line By Line
    myArray[i]= strLine;
    i++;
    }
    // bubble sort
    for(i=0; i<myArray.length; i++){ // while there are still lines left
    for(int j=i+1; j<myArray.length; j++){
    if(myArray[j].compareToIgnoreCase(myArray[i].toString())){ // where the problem is
    swap(myArray,i,j);
    }
    }
    }
    br.close(); //Close the input stream
    }
    }
