Answer:
Pair Programming
Explanation:
In Extreme Programming XP, pair programming is a practice in which two programmers work together in a pair at one machine, when writing a code.
One of the two programmers is called the "driver" or developer who writes the code and supervises all the changes made to the program.
The other one is called an "navigator" or observer who provides ideas on how the program should be written, observes or reviews it the program, identify the issues or errors in the code, help in code simplifications.
The two developers implements the program, do coding, review the program and check each other's work. They both are required to be equally skilled in order to implement and test the code. This improves the process of the software development. By working in a pair and reviewing and testing the code together, they develop a better code.
Answer:
- import java.util.Random;
- import java.util.Arrays;
- public class Main {
-
- public static void main(String[] args) {
- int n = 10;
- int [] myArray = new int[n];
- buildArray(myArray, n);
- System.out.println(Arrays.toString(myArray));
- }
-
- public static void buildArray(int[] arr, int n){
- for(int i=0; i < arr.length; i++){
- Random rand = new Random();
- arr[i] = rand.nextInt(90) +10;
- }
- }
- }
Explanation:
Firstly, create a method buildArray that take two inputs, an array and an array size (Line 12). In the method, use random nextInt method to repeatedly generate a two digit random number within a for loop that will loop over array size number of times (Line 13-15). The expression rand.nextInt(90) + 10 will generate digits between 10 - 99.
In the main program, call the build array method by using an array and array size as input arguments (Line 8). At last, print the array after calling the buildArray method (Line 9).
Answer:
The Proper codes in Line a and Line b is given below
average=Sum/3
print (" Average is = ", average)
Explanation:
In the given question it calculated the sum but the program does not calculate the average of the 3 numbers.The average of the 3 number is calculated by using average=Sum/3 statement so we add this code in Line a then After that print the value of average by using the print function so we add this code in Line b.
Answer:
public static void main(String[] args) {
String ing[] = {"ten","fading","post","card","thunder","hinge","trailing","batting"};
for (String i: ing){
if (i.endsWith("ing")){
System.out.println(i);
}
}
}
Explanation:
The for-loop cycles through the entire list and the if-statement makes it so that the string is only printed if it ends with "ing"
