The typical ranges for integers may seem strange but are derived from

Base 10 floating-point precision

Overflows

Powers of two because of base 2 representation within the computer

10.

Which of the following statements is correct about constants?

You can make a variable constant by using the final reserved word when declaring it.

Constants are written using capital letters because the compiler ignores constants declared in small letters.

Constant variables can only be changed through the Math library.

The data stored inside a constant can be changed using an assignment statement.

10.Given the definition final double PI = 3.14159; which of the following is the Java equivalent of the mathematical expression c = radius2

A.c = Math.PI * Math.pow(2, radius);

B.c = Math.PI * Math.pow(radius, 2);

C.c = Math.pow(Math.PI * radius, 2);

D.c = Math.PI * (radius * 2);

h = 4ab – 2b / c

h = (4ab – b2) / c

h = (4ab – 2b) / c

h = 4ab – b2 / c

Explanation / Answer

1. option C

2. opion B

4. Option c (25)

This produces the result.System.out.println("ABCDE"\");

10. A (we can make a variable constant by declaring it with a key wrd called FINAl
