What is the output of the Java code given below?

String color[] = {"Blue", "Red", "Violet"};
System.out.println(color[2].length());

1. 6
2. 5
3. 3
4. 2

Define a class to accept values into 4x4 array and find and display the sum of each row.

Example:

A[][]={{1,2,3,4},{5,6,7,8},{1,3,5,7},{2,5,3,1}}

Output:

sum of row 1 = 10 (1+2+3+4)
sum of row 2 = 26 (5+6+7+8)
sum of row 3 = 16 (1+3+5+7)
sum of row 4 = 11 (2+5+3+1)

Define a class to accept values into an integer array of order 4 x 4 and check whether it is a DIAGONAL array or not. An array is DIAGONAL if the sum of the left diagonal elements equals the sum of the right diagonal elements. Print the appropriate message.

Example:

3 4 2 5
2 5 2 3
5 3 2 7
1 3 7 1

Sum of the left diagonal element = 3 + 5 + 2 + 1 = 11

Sum of the right diagonal element = 5 + 2 + 3 + 1 = 11

Name the below structure:

1. One dimensional array
2. Two Dimensional array with 4 rows and 5 columns
3. Three dimensional array
4. Two Dimensional array with 5 rows and 4 columns
