Which One of the following Array Declaration Statement Is Not Legal
Option A is correct. A public access modifier is acceptable. Method prototypes in an interface are all abstract because of their declaration and should not be declared abstract. What valid declarations exist in an interface definition? Option C is incorrect because it indicates a declaration of a legal table without initialization. Which of the following options does an array declare and initialize with five numbers? (1), (2) and (3) are correct. Interfaces can have constants that are always implicitly public, static, and definitive. Public, static, and final interface constant declarations are optional in any combination. 1) What is the value of a[1] after running the following code? int[] a = {0, 2, 4, 1, 3}; for(int i = 0; i a[i] = a[(a[i] + 3) % a.length]; No, it is not possible to create zero-length arrays in Java. (3) and (5) are incorrect because you cannot declare a table of only one size. Size is only necessary if the array has actually been instantiated (and the JVM needs to know how much space to allocate to the array, depending on the array type and size).
What statement is true in light of the following program? Which of these table declaration instructions are not legal? The size of the table cannot be specified as indicated in points (b) and (e). 5) What is the result of this program? class array_output { public static void main(String args[]) { int array_variable [] = new int[10]; for (int i = 0; i { array_variable[i] = i; System.out.print(array_variable[i] + ” “); i++; } } } Member declarations in an interface do not allow the use of certain declaration modifiers. You cannot use Transient, Ephemeral, or Synchronized in a member declaration in an interface. In addition, you should not use private and protected identifiers when declaring members of an interface. The D option is incorrect (and does not compile) because it declares an array with a size. Tables should never be given a size when they are declared. (1), (3) and (6) are correct. character C1 = 064770; is an octal representation of the integer value 27128, which is legal because it fits into an unsigned 16-bit integer. char c3 = 0xbeef; is a hexadecimal representation of the integer value 48879 that fits in a 16-bit unsigned integer.
char c6 = `uface`; is a Unicode representation of a character. Yes, you can create zero-length arrays of any type. The A option is incorrect because it shows an example of instantiating a class named Array, passing an integer value of 5 to the object`s constructor. If you don`t see the brackets, you can be sure that there is no real array object! In other words, an Array object (an instance of the Array class) is not the same as an Array object. (1), (2) and (4) are legal statements. You can use a table declaration to place square brackets to the right or left of the identifier. Option A sounds strange, but it`s perfectly legal to divide parentheses into a multidimensional array and place them on either side of the identifier. Although programming this way would only annoy your fellow programmers, for the exam you should know that it is legal. 4) Which of the following statements is valid? No, you cannot create zero-length arrays, but the main() method can pass a zero-length array with string references if no program arguments are specified. The size of an array is always associated with the instance of the array (right), not the table reference (left).
2) To declare a one-dimensional array, use this general form The code cannot be compiled because the int[] array type is incorrect. The size of the array is implicitly specified by the initialization code. What would be the result of trying to compile and run the following program? Option B is the legal way to declare and initialize a five-element array. For the following declaration, which expression returns the size of the array, assuming the array has been initialized? The program throws a NullPointerException exception if it is executed with NULL program arguments. char c5 = `iface`; is incorrect because it appears to be a Unicode representation (note the backslash), but starts with `i` and not `u`. Water and sulfur dioxide are both polar molecules and their geometry is similar. Why is SO2mathrm{SO}_2SO2 not considered the main greenhouse gas? Refer to the role of the mouth, stomach, small intestine and colon in digesting a slice of cheese pizza. अगर आप कम्पटीशन एग्जाम की ऑनलाइन तैयारी कर रहे है तो यहाँ से आप फ्री में Online Test.
Option C is incorrect. static refers to the class, not an instance. tank c2 = `face`; is incorrect because you cannot insert more than one character into a character literal. The only other acceptable character literal that can be enclosed in single quotes is a Unicode value, and Unicode literals must always begin with a `u`. Where are geophysical disasters such as volcanoes and earthquakes most likely? One. Ancient inland seas, b. areas with moderate temperatures, c. Boundary of river delta plates. The program cannot be compiled due to uninitialized variables. The program returns “no arguments” and “two arguments” when called with zero or three program arguments, respectively.
The program compiles but throws an ArrayIndexOutOfBoundsException exception when executed. Imagine a coal-fired steam plant that produces 175 MW of electricity. The plant operates on a simple ideal Rankine cycle with turbine inlet conditions of 7 MPa and 550∘C550^{circ} mathrm{C}550∘C and a capacitor pressure of 15 kPa. Coal has a calorific value (energy released during fuel combustion) of 29 300 kJ/kg. Assuming that 85% of this energy is transferred to steam in the boiler and that the electric generator has an efficiency of 96%, determine (a) the overall efficiency of the facility (the ratio of net electricity generation to energy input as fuel) and (b) the rate of coal supply required. char c4 = u0022; is wrong because the single quotation marks are missing. The program compiles and runs without errors, but produces no output. Option B is incorrect.
The last modifier means that this method cannot be constructed in a subclass. A final method cannot be abstract. Option D is incorrect. protected is not allowed when declaring a method of an interface. See information below.
