Your lab is to write code in the class below the numbered comments in your project. Here are the instructions and do them in the order given.

1 . Write statement(s) that will get an input of a name from TextInputDialog object and assign the input to the object/variable (which is already declared and created) nameString

2. Write statement(s) that will get an input of a integer from Scanner object and assign the input to the variable (which is already declared and created) number1Integer.

3. Write statement(s) that will get an input of a integer from Scanner object and assign the input to the variable (which is already declared and created) number2Integer .

4. Write statement(s) that will now that will add the variables number1Integer and number2Integer and assign the result to the variable (which is already declared and created) sumInteger.

5. Write statement(s) that will now that will subtract the variables number1Integer and number2Integer and assign the result to the variable (which is already declared and created) differenceInteger.

6. Write statement(s) that will now that will multiply the variables number1Integer and number2Integer and assign the result to the variable (which is already declared and created) productInteger.

7. Write statement(s) (figure out a mathematical expression) that will give you the hours that are in totalMinutesInteger (which is already declared and created and holds the number 215) assign the hours to the variable (which is already declared and created) hoursInteger.

8. Write statement(s) (figure out a mathematical expression) that will give you the remaining minutes from the hours calculate that are in totalMinutesInteger (which is already declared and created and holds the number 215) assign the remaining minutes to the variable (which is already declared and created) minutesInteger.

8. Now you will be writing code to display what you have processed. The addition operation is done for you. You must follow the same format for subtract, multiply and find the hours and minutes under the respective comments

9. Write statement(s) that will display the results that you have calculated. The nameString and sumInteger are already displayed in the their respective labels

a. Write statement(s) that will display differenceInteger in differenceLabel

b. Write statement(s) that will display productInteger in multiplyLabel

c. Write statement(s) that will display hoursInteger in hoursLabel

d. Write statement(s) that will display minutesInteger in minutesLabel
