Answer:
- public class Main {
-
- public static void main (String [] args) {
- int[][] myArray = {{1,5,6}, {7, 9, 2}};
- fixArray(myArray, 1, 2, 12);
-
- System.out.println(myArray[1][2]);
- }
-
-
- private static void fixArray(int[][] array, int row, int col, int value){
- array[row][col] = value;
- }
- }
Explanation:
The solution code is written in Java.
Firstly, create the method fixArray with that takes four inputs, array, row, col and value (Line 11). Within the method body, use row and col as index to address a particular element from array and set the input value to it (Line 12).
Next, we test the method in the main program using a sample array (Line 4) and we try to change the row-1 and col-2 element from 2 to 12 (Line 5).
The print statement in Line 7 will display 12 in console.

Explanation:
//Program is written in Java.
public void first three elements(int[] nums){
int I;
//Check if array has up to three elements
if(nums.length > 3){
for(I = 0; I < nums.length; I++){
while (I < 3){
System.out.println(nums [I]);
}
}
else{
System.out.print("Array does not contain up to three elements");
}
}

Technology: What Is It?
Technology is the systematic and repeatable body of scientific to achieve practical objectives. The result of such an effort is sometimes known as technology. The use of tech is pervasive in many areas, including daily life, science, industry, communication, and transportation. Both real things like the machines or the utensils and intangible tools like software are considered technologies. Computer technology (IT) is indeed the practice of creating, processing, storing, retrieving, and exchanging various types of data and information using computers. Technology used for information and communications includes IT.
