Question

Four diferent games offer to play: Three number, Four number, Five number and Five Number +1 lotteries. each game have independent numbers.

develop an application that randomly piks numbers for all four games and display the generated numbers in a GUI.

Three number requires players to choose three numbers in the range from 0-9.

Four number requires players to choose four numbers in the range from 0-9.

Five number requires players to choose five numbers in the range from 1-36.

Five number +1 requires players to choose five numbers in the range from 1-39 and a additional number from 1-42

1.) Generating Random numbers

  Cfreate a method in line 142 named generate that will take two ints representing the low and hidh end of range of random numbers, and return a String containing a generated random number.

2.) Drawing numbers for the games.

Add code to the generateJButtonActionPerformed method to call the generate method and display the generated numbers for all four games. Some lotteries allow repetition of numbers. To make this application simple allow repetition of numbers for all the lotteries.

Explanation / Answer

// generate random lottery numbers

private void generateJButtonActionPerformed( ActionEvent event )

{

output3JTextField.setText(generate(0, 9));

output4JTextField.setText(generate(0, 9));

output5JTextField.setText(generate(1, 36));

output5Plus1JTextField.setText(generate(1, 39));

outputExtra1JTextField.setText(generate(1,42));

} // end method generateJButtonActionPerformed

############generate method #######################

//line 142

public static String generate(int low,int high){

//low + (int)(Math.random()*high;

return Integer.toString(low + (int)(Math.random()*high));

}
