Figured so.

You need to ensure the encoding is the same on the send and receive. Have you thought of using a session variable of type String[]. You can make it multidimensional and could bind it to your grid.

Have you tried: SELECT COUNT(column_name) FROM table_name; ?

int rows = 3;

String[] selections = new String[3];
int selectionIndex = 0;

for(int i = 0; i < rows; i++){
for(int j = 0; j < columns; j++) {

String message = menuArray[i][j];
int min = Integer.parseInt(menuArray[i+1][j+1]);
int max = Integer.parseInt(menuArray[i+2][j+2]);
int output = MenuHelperClass.displayMenu(message, min, max);
selections[selectionIndex] = Integer.toString(output);
selectionIndex++;

System.out.println( "\n" );
}

String selectedValues = "";
for(int z=0; z < 3; z++){
selectedValues += selections[z] + ", ";
}
System.out.println("You selected options "+ selectedValues +" for your choices.");
}

}

If you could figure out the readline part, it should work. Might need alittle more debugging.

Have you tried powershell? Dont know how you can get that granular.

Are you trying to compare the columns or the rows? Also, do you have a sample file?
