Create a Java application that would allow a person to practice math (either addition, subtraction, multiplication or division). The questions must be randomly generated ( the values for each number should be in the range from 1 to 10). In total, 10 questions should be asked. After 10 questions are asked and answered, display a message to the user that would state either ?Good Job? if the ratio of correct to incorrect answers exceeds 70% or you would do better next time if the ratio is smaller than 70%.

this is what i got so far. so basically what i did is i used the java palletes to make a application and put two buttons one button makes two random numbers and the other button tells if u got it right or wrong and also i gave them some coding but i can't make it do only 10 questions for button1 and not able to add them so i can get answers.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

    Random rand = new Random();
    for(int i = 0;i <= 10;++i){
        int rad = rand.nextInt(10)+1;
        jLabel4.setText("" + rad);
        jLabel6.setText("" + rad);
    }    
}                                        

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    try{
        int num = Integer.parseInt(jLabel4.getText());
        int num1 = Integer.parseInt(jLabel6.getText());
        int num2 = Integer.parseInt(jTextField1.getText());

        if(evt.getSource() == jButton2){
            num2 = num + num1;
            jLabel2.setText("Good job!");
        }else
            num2 = num - num1;
            jLabel2.setText("Try Again");

        }catch(Exception e){
            JOptionPane.showMessageDialog(null, "Numbers only");
        }
}
