    Default Search for min and max values as columns position in array

    Hi all,

    I have an array such this simple example

    double[][]array = {{10.3,10.8,10.1,10.5},{9.3,9.8,9.1,9.5},{11.3,10.8,10.6,10.5}};
            for(int i=0;i<array.length;i++){
                for(int j=0;j<array[i].length;j++){
                    System.out.print(array[i][j]+" ");
                }
                System.out.println("");
            }

    I need to find columns position for min and max values, no need to get the values itself.

    I my example, max should always be at j[1] and min at j[2]: if not, print an error message such as: "Warning!Error at line 2".

    Thanks for any help

    Susie

    What have you tried? Where are you stuck? How would you do this "by hand", without a computer?

    Would seek row by row and chech if value at column[1] is greater than any other columns value in the same row.
    Same for value at column[2] and there must be no lower value than this.

    Is this correct?

    Well, do you know how to find the highest and lowest values in the array? I would start there.
