intro to java problem for school

**Can someone help me with this problem? The trouble I'm having is with the end with (“Congratulations!” or "Please ask your teacher for help", depending on whether the**

student gets more than 7 correct answers or not).

Suppose you are asked to design a software tool that helps an elementary school student learn

arithmetic operations. The software allows the student to select the arithmetic operation she or he

wishes to study. The student chooses from a menu one of two arithmetic operations: 1) addition,

2) subtraction

Based on the student choice, the software tests the user with exactly 10 questions. For each

question, two random positive one-digit integers are generated; then the student is asked to enter

the answer for the arithmetic operation applied to the two numbers.

The software displays a message “Congratulations!” if more that 7 questions are answered

correctly, otherwise, the program should display "Please ask your teacher for help".

Question 1 (40 points)

a) Write a problem-solving algorithm to execute the arithmetic test for a student for addition

or subtraction operations. The algorithm receives an integer that represents the required

operation from the main algorithm (1 for addition and 0 for subtraction). The algorithm

then gets the student to answer 10 questions as follows:

a. Randomly generates two positive one-digit integers.

b. Ask the student to enter the answer for the arithmetic operation of the two

numbers,

c. Checks if the result is true.

As questions are answered, the correct answers are counted. The number of correct

answers is returned to the calling algorithm.

b) Create a main algorithm to interact with the student to obtain the choice for either

addition or subtraction and produce the results for a student and then calls the algorithm

developed in part (a) to test the student (recall this algorithm returns the number of

correct answers). The main algorithm prints one of two possible messages to the student

(“Congratulations!” or "Please ask your teacher for help", depending on whether the

student gets more than 7 correct answers or not).

Implement in Java the algorithms you designed
