Question 5 :- first option grades[ i ][ j ] is correct
Reason:- given row index= i and column index = j
In two dimensional array we use the following syntax to represent row index and column index in a 2D array
syntax:- datatype array_name[row_index][column_index];
grades[ i ][ j ]; is correct syntax to use
Question 6:- option d all of these are errors in syntax is correct
Reason :- given datatype [ 4][ 0 ][ 3 ] arrayNam:
according syntax it should contain only two brackets for row and column indexes respectively and a syntax should not end with colon

True False QUESTIONS An ArrayList object reference of Book objects named books has already been declared. How do you instantiate it using the ArrayList default constructor? books = new ArrayList: books new Book(). books = new ArrayList<Book>(); books - new <Book>ArrayList();
Given the following construct a UML diagram for Java: Design a class named location for locating a maximal value and its location in a two-dimensional array. The class contains public data fields row, column, and maxValue that store the maximum value and its indices in a two-dimensional array with row and column as int types and maxValue as double type. Write the following method that returns the location of the largest element in two-dimensional array: Public static Location locateLargest(double[][] a)...

Write the line that declares a two-dimensional array of strings named chessboard. That is, how would I declare a two-dimension array of strings that is called chessboard? You would declare a String array by saying " String []" correct? Now that's just a single array. How can I make that a two-dimension array? And how would I name it chessboard? Write the line that declare and creates a two-dimensional array of chars, tictactoe, with 3 rows, each with 3 elements...
Using Java. Write a program that creates a “triangular” two-dimensional array A of 10 rows. The first row has length 1, the second row has length 2, the third row has length 3, and so on. Then initialize the array using nested for loops so that the value of A[i][j] is i+j. Finally, print out the array in a nice triangular form.
