You are going to fill in the blanks.

You will complete the MarkSymbol class:

Code a program which will input a mark, then display a symbol for this mark according to this table.

public class _____

To input a mark (fill in missing code):

int mark = ______(JOptionPane.showInputDialog("Input number));

We need to declare a variable to store the symbol:

____ symbol = ' ';

Complete the if:

if (mark __ 80)

{

symbol = 'A';

}

The next part of the laddered if:

else if (mark >= __ )

{

symbol = 'B';

}

The next part of the laddered if:

else if (mark >= 60 )

{

symbol = ___;

}

The next part of the laddered if:

else if (_____ >= 50 )

{

symbol = 'D';

}

To end off the laddered if,

(all other marks get an 'E'):

____

{

symbol = 'E';

}

The Output at the end of the class:

System.out.println("Your symbol: " + ____ );
