Which of these table declaration instructions are not legal? The size of the array is implicitly specified by the initialization code. D – This creates an array of length 4. Each element in this array is null. However, you can assign an ints array of any length to each element. Example: a[0] = new int[10];//valid a[1] = new int[4];//valid a[2] = new int[]; invalid because you must specify the length a[3] = new Object[] //invalid, because a[3] can only refer to an array of ints. This shows that when creating a one-dimensional array, the length must be specified, but when creating multidimensional arrays, the length of the last dimension cannot be specified. In addition, the length of several larger dimensions after the first cannot be specified even if none of the dimensions are specified later. For example, a[][][][][] = new int[4][3][3][5]; is the same as a[][][][] = new int[4][][][][]; (Note that the first dimension must be specified.) Therefore, multidimensional arrays do not need to be symmetrical. Which of the following code fragments correctly initializes a two-dimensional array of characters named cA with a size that refers to cA[2][3] to a valid element? 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++; } } } int[] ia, ba; Here, IA and BA are both int. int ia[], ba; Here there is only the AI table int and ba is an int. The size of the table cannot be specified as indicated in points (b) and (e). The notation [] can be placed both before and after the variable name in an array declaration. The size of an array is always associated with the instance of the array (right), not the table reference (left).

Multidimensional arrays are created by creating tables that can contain references to other tables. A – This creates an array of length 5. Each element of this array is an array of 4 ints. 2) To declare a one-dimensional array, use this general form Which of the following correctly declares a variable that can contain an array of 10 integers? 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 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]; 4) Which of the following statements is valid? 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. A. int[ ] a[ ] = new int [5][4]; B. int a[ ][ ] = new int [5][4]; C.

int a[ ][ ] = new int [ ][4]; D. int[ ] a[ ] = new int[4][ ]; E. int[ ][ ] a = new int[5][4]; Which of the following options is not problematic at compile time or run-time? One. It does not compile. B. At run time, a NullPointerException exception is thrown. C. An IndexOutOfBoundsException exception is thrown at run time. O.C. 222 E.

null. One. int[ ] i[ ] = { { 1, 2 }, { 1 }, { }, { 1, 2, 3 } }; B. int i[ ] = new int[2] {1, 2}; C. int i[ ][ ] = new int[ ][ ] { {1, 2, 3}, {4, 5, 6} } ; D. int i[ ][ ] = { { 1, 2 }, new int[ 2 ] }; E. int i[4] = { 1, 2, 3, 4 } ;. One.

daaa[0] = d; B. daaa[0] = daa; C. daaa[0] = daa[0]; D. daa[1][1] = d; E. daa = daaa[0]. Water and sulfur dioxide are both polar molecules and their geometry is similar. Why is SO2mathrm{SO}_2SO2 not considered the main greenhouse gas? double daaa[][][] = new double[3][][]; double d = 100.0; double[][] daa = new double[1][1]; 1. char[][] cA = { { `a`, `b`, `c` }, { `a`, `b`, `c` } }; 2.
