## Java Problem Set 1 – Variables, Math, Output

Create a new class called VarsAndMath. Write the code for 1-4 in the same class/program. Label each section with a System.out.println() statement.

1. Write code that has two

*integers (num1 and num2)*, adds them, stores the result in a variable (sum) then prints out in the format below.Number 1: 30

Number 2: 20

Sum: 50

2. Write code that has two

*doubles**(num3 and num4)*, subtracts them, stores the result in a variable (diff) then prints out in the format below.Number 1: 30.0

Number 2: 20.0

Difference: 50.0

3. Write code that takes 10

*integers (grade1, grade2, etc.)*and prints out the average in both integer and decimal form. See output below.Ten Grades: 90, 50, 83, 74, 99, 100, 0, 96, 89, 93, 91

Average (whole): 86

Average (decimal): 86.5

4. Write code that computes the Pythagorean theorem. Given is A and B. Find C.

C = math.sqrt(A*A + B*B)

C = math.sqrt(A*A + B*B)

A: 5.0

B: 12.0

C: 13.0

Output should look like:
