False.
- It need three for loops.
- If it is a two dimensional array then it needs double for loop.
- After the third loop write the logic of required operation.
12.
False
- The elements of numeric type are not initialise to NULL it is initialise with some numeric value.
- By default it store some garbage value in the multidimensional array.
- The instantiated variables receive the numerical values when it is called.

Q1) How would you declare an array of doubles called myDoubles? Arrays can be initialized in one of two ways. In one method, the array elements are placed in a list enclosed in curly braces after the array name definition. For example, the code below creates an array of ints with 3 elements: 1, 2 and 3. int[] a = {1, 2, 3, 4}; We can also initialize an array with a new construct, indicating how many elements we want...

State whether each of the following is true or false. If false, explain why: a.Referring to an array element outside the array bounds is a syntax error. b.When initializing an array at its declaration, it is a syntax error to provide less initializers than the number of array elements. c.A character array can be initialized using a string literal. d.An individual array element that is passed to a function and modified in that function will contain the modified value when...

In Java: Create an array of Integers with 10 elements, loop (use a for loop) through the array of integers printing their values to the screen. Create an array of Strings with 10 elements, loop (use a for loop) through the array of Strings printing their values to the screen. Finally, create an ArrayList of Integers. Use the loop from part 1 above and add each integer as you print it to the ArrayList as well, then start a final...

Write a java program that specifies three parallel one dimensional arrays name length, width, and area. Each array should be capable of holding a number elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values in the length and width arrays (thus, area[i] = length [i]* width [i]) after data has been entered display the following output: (in Java)
