Hi!!
I need help in writing a program that will help an elimentary school student learn multiplication, using Math.random to produce two positive one-digit integers. The student then types the answer into a text field and the program checks the student's answer, if its correct it displays the string "Very Good" in the browser status bar and generate a new question. If the answer is wrong, it displays the string "Please try again" and lets the student tries the same question repeatedly until he/she gets the right answer.
I have to use "switch" structure to issue four different correct and incorrect responses. And also, i have to use GUI in developing the program.

Any help will be appreciated.
Thanks.

int answer = Integer.parseInt(reader.readLine().trim());

System.out.println("Very Good");
