Answer:
import java.util.*;
public class Country
{
public static void main(String args[])
{
char ch,temp;
int flag = 0;
String country;
ArrayList<String> countries = new ArrayList<String>();
Scanner sc = new Scanner(System.in);
do
{
System.out.println("enter the country you have visited:\t");
country = sc.next();
for(int i=0;i<countries.size();i++)
{
if(countries.get(i).equals(country))
{
System.out.println("you have already entered the country");
flag = 1;
break;
}
}
if(flag == 0)
{
countries.add(country);
flag = 0;
}
System.out.println("want to add another country(y/n):\t");
ch = sc.next().charAt(0);
}while(ch!='n');
Collections.sort(countries);
System.out.println("Countries you have visited:\t"+countries);
System.out.println("Total number of contries visited:"+countries.size());
}
}
Explanation:
Answer:
public class Main
{
public static void printString(String strText, int intNumber) {
for(int i=0; i<intNumber; i++){
System.out.println(strText);
}
}
public static void main(String[] args) {
printString("Brainly", 3);
}
}
Explanation:
- Define a function called <em>printString</em> that takes two parameters - a String and an int. Since the function will print out the given String, it's type will be <u>void</u>.
- Use <em>for loop</em> to iterate according to the given number and print the given string
- In the main, call the <em>printString </em>function with some parameters.
Answer:
utilities
Explanation:
the other 3 are Cs programs
Answer:
//variable integer_list to hold a list of integers
DECLARE integer_list
ASSIGN values to integer_list
//variable sum to hold the sum of the elements in the list
DECLARE sum
ASSIGN zero to sum
//loop through the integer_list and sum all it's elements together.
for(int i=0; i<integer_list.size(); i++){
sum += interger_list.get(i)
}
//Show the result of the addition from the for loop
DISPLAY "The sum is " + sum
Explanation:
The above code uses some hypothetical programming language syntax. The second and third lines declare an arbitrary integer list and assign a set of values to it respectively.
The fifth line declares a variable "sum" which will hold the result of summing all the elements in the list. The sixth line initializes "sum" to zero.
The for loop shown iterates through the integer list cumulatively summing its elements.
The result is displayed as written on line 12.
Hope it helps!
