Looping - Practice Answers

Question 1 Solution:

import java.util.Scanner;

class FirstLooping{
public static void main(String args[]){
Scanner input = new Scanner(System.in);
int sum = 0;
for(int i = 0; i < 100; i++){
int number = input.nextInt();
sum = sum + number;
}
System.out.println("total sum is: " + sum);
}
}

Question 2 Solution:

import java.util.Scanner;

class SecondLooping{
public static void main(String args[]){
Scanner input = new Scanner(System.in);
int sum = 0;
int average;
for(int i = 0; i < 50; i++){
int number = input.nextInt();
sum = sum + number;
}
average = sum / 50;
System.out.println("The sum is: " + average);
}
}


Question 3 Solution:

import java.util.Scanner;

class ThirdLooping{
public static void main(String args[]){
Scanner input = new Scanner(System.in);
int sum = 0;
for(int i = 0; i < 20; i++){
int number = input.nextInt();
sum = sum + number;
}
for(int i = 0; i < 10; i++){
int number = input.nextInt();
sum = sum - number;
}
System.out.println("Your total is: " + sum);
}
}
