You coded the following in class Test.java:
int a = 5;
a =+ 3;
System.out.println("The value of a is " + a);
The code compiles properly and runs, but the result is not what you expected. The output is,
The value of c is 3
You expected the value of a to be 8. Explain what the problem is and how to fix it.

- You are responsible for writing the code necessary to perform a measurement unit conversions. In other words, the input will be a measurement in one unit, and you will have to convert it to an equivalent measurement in a different set of units. How might you approach such a problem? How might you structure your solution?

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.
