Here's the best answer I can give you, but bear with me.
The second option is incorrect because a class method must have a class identifier not an object identifier. What makes myObject an object identifier is the fact that it was created as an instance of the class MyClass in the constructor in line 5 (MyClass myObject= new MyClass(12.4,20);
The answer here should be MyClass.method2(20); Methods must have a set of parentheses, even if it has nothing inside. The first answer has a class identifier but the SOME_VALUE acts much like the Integer.MAX_VALUE; code which stores a constant value and does not actually perform tasks like most methods.
In short, the answer should be the last one but I hope my explanation cleared some things up for you, even if it was a bit more concept heavy than the question probably intended.

Assume the following JavaScript program was interpreted using staticscoping rules. What value of x is displayed in function sub1

Annette [7]

Answer:

Static scoping: x is 5

Dynamic scoping : x is 10.

Explanation:

Static scoping :

In static scoping the variable of a function take the value within the function.

If there is no values exist within the function then take the global value of the variable.

var x // No value is assigned to x so it check global value of x

function sub1() {

document.write(“x = “ + x + “”); // So it print x = 5

}

function sub2() {

var x;

x = 10;

sub1();

}

x = 5; // It is the global value of x

sub2();

Static scoping: x is 5

Dynamic scoping :

In Dynamic scoping the variable of a function take the value all the calling function ends.

If the global value is the last assigned value of a variable then it take that value.

If there exist some other function after global variable value if that function contain the variable with some assigned value variable take that value.

var x

function sub1() {

document.write(“x = “ + x + “”);

}

x = 5; // At this point x value is 5 and check there exist a function

sub2(); // So now call this function

function sub2() {

var x;

x = 10; // The value of x = 5 is replaced with x = 10

sub1();

}

Dynamic scoping : x is 10.

A computer has a word length of 8 bits (including sign). if 2’s complement is used to represent negative numbers, what range of

iVinArrow [24]

Two's-complement notation can represent all integers from - 2^(N-1) to 2^(N-1) - 1, where N is the word length of the computer. So, in your example, the computer could store all integers from -128 to 127 inclusive.

Answer:

125.28₁₀ in hexadecimal = 7D.47AE147AE1₁₆

Step-by-Step Explanation:

To convert decimal number 125.28, we convert its integer and fraction part individually and then add them to get the equivalent hexadecimal number, as below:

To convert integer 125 to hexadecimal, follow these steps:

Divide 125 by 16 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent hexadecimal number.

125 / 16 = 7 with remainder 13 (D)

7 / 16 = 0 with remainder 7

Here is the answer to 125 decimal to hexadecimal number:

For converting decimal fraction 0.28 to hexadecimal number, follow these steps:

Multiply 0.28 by 16 keeping notice of the resulting integer and fractional part. Continue multiplying by 16 until you get a resulting fractional part equal to zero (we calcuclate upto ten digits).

Then just write out the integer parts from the results of each multiplication to get equivalent hexadecimal number.

0.28 × 16 = 4 + 0.48

0.48 × 16 = 7 + 0.68000000000001

0.68000000000001 × 16 = 10 (A) + 0.88000000000011

0.88000000000011 × 16 = 14 (E) + 0.080000000001746

0.080000000001746 × 16 = 1 + 0.28000000002794

0.28000000002794 × 16 = 4 + 0.48000000044703

0.48000000044703 × 16 = 7 + 0.68000000715256

0.68000000715256 × 16 = 10 (A) + 0.88000011444092

0.88000011444092 × 16 = 14 (E) + 0.080001831054688

0.080001831054688 × 16 = 1 + 0.280029296875

Here is the answer to 0.28 decimal to hexadecimal number:

0.47AE147AE1

Therefore, decimal number 125.28 converted to hexadecimal is equal:

7D.47AE147AE1
