Sum the elements of an array
This program reverses every word of a string and display the reversed string as an output. For example, if we input a string as "Reverse the word of this string" then the output of the program would be: "esrever eht drow fo siht gnirts".
Program 1: No user interaction
class SumOfArray{
public static void main(String args[]){
int[] array = {10, 20, 30, 40, 50, 10};
int sum = 0;
//Advanced for loop
for( int num : array) {
sum = sum+num;
}
System.out.println("Sum of array elements is:"+sum);
}
}
Output
Sum of array elements is:160
Program 2: User enters the array’s elements
import java.util.Scanner;
class SumDemo{
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
int[] array = new int[10];
int sum = 0;
System.out.println("Enter the elements:");
for (int i=0; i<10; i++)
{
array[i] = scanner.nextInt();
}
for( int num : array) {
sum = sum+num;
}
System.out.println("Sum of array elements is:"+sum);
}
}
Output
Enter the elements:
