Solution
i) One-dimensional Array: In the context of Java programming, a one-dimensional array is a data structure that stores a fixed-size sequence of elements of the same type. It is also known as a single-dimensional array. The elements in a one-dimensional array are accessed using an index, starting from 0.
To demonstrate the implementation of a one-dimensional array in Java, you can use the following code snippet:
// Declare and initialize a one-dimensional array
int[] numbers = {1, 2, 3, 4, 5};
// Access and print the elements of the array
for (int i = 0; i < numbers.length; i++) {
System.out.println(numbers[i]);
}
ii) Two-dimensional Array: In Java programming, a two-dimensional array is a data structure that stores elements in a grid-like format with rows and columns. It is also known as a matrix. Each element in a two-dimensional array is accessed using two indices - one for the row and another for the column.
To demonstrate the implementation of a two-dimensional array in Java, you can use the following code snippet:
// Declare and initialize a two-dimensional array
int[][] matrix = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
// Access and print the elements of the array
for (int i = 0; i < matrix.length; i++) {
for (int j = 0; j < matrix[i].length; j++) {
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}
This code snippet declares and initializes a two-dimensional array called matrix with 3 rows and 3 columns. It then uses nested loops to access and print each element of the array.
