Can you create a 2 dimensional array with different types?

You can even create a two-dimensional array where each subarray has a different length or different type, also known as a heterogeneous array in Java. This means it’s possible to create a two-dimensional array with variable column length in Java.

Can we create a 2D array with different row size?

Arrays of arrays of different size is possible in C. Simply they are not 2D arrays but arrays or pointers.

Can a matrix have multiple dimensions?

A multidimensional array in MATLAB® is an array with more than two dimensions. In a matrix, the two dimensions are represented by rows and columns. Each element is defined by two subscripts, the row index and the column index. A 3-D array, for example, uses three subscripts.

How do you create an array with different data types?

You can create an array with elements of different data types when declare the array as Object. Since System. Object is the base class of all other types, an item in an array of Objects can have a reference to any other type of object.

How do you establish a parallel relationship between two or more arrays?

How do you establish a parallel relationship between two or more arrays? Establishing parallel relationship between two or more arrays can be done by using the same subscript value for each array.

How do you instantiate a two dimensional array in Java?

Two – dimensional Array (2D-Array)

1. Declaration – Syntax: data_type[][] array_name = new data_type[x][y]; For example: int[][] arr = new int[10][20];
2. Initialization – Syntax: array_name[row_index][column_index] = value; For example: arr[0][0] = 1;

How do you initialize a two dimensional array during declaration?

Like the one-dimensional arrays, two-dimensional arrays may be initialized by following their declaration with a list of initial values enclosed in braces. Ex: int a[2][3]={0,0,0,1,1,1}; initializes the elements of the first row to zero and the second row to one. The initialization is done row by row.

How do you find the dimensions of two matrices?

You take the number of rows from the first matrix (2) to find the first dimension, and the number of columns from the second matrix (2) to find the second dimension. Another way to think of this: The dimensions of their product is the two outside dimensions.
