Java program to calculate sum in array elements
Java program to calculate sum in array elements
In this tutorial, we will discuss the Java program to calculate sum in array elements
In this topic, we can learn how to calculate the sum of array elements.
Calculate the sum of array elements
Calculate the sum of array elements Using for loop
This is a Java program used to create an array and calculate sum the array elements. This program refers to a one-dimensional array(array is a group of elements are referred to by single name) in Java language and explains how to find the sum of numbers in array.
class Array_Sum{
public static void main (String args[]){
int[] marks ={45,56,67,78,48,90,47,87};
//diclaration and creation array
int sum=0;//declare and initialize sum
for(int i=0; i<=7; i++){
sum=sum+marks[i];//find sum using loop
}
System.out.println("Sum of array elements:"+sum);
}//display the sum on screen
}
When the above code is compiled and executed, it produces the following results
Sum of array elements:518
Program 2
This is a Java program to takes input(Array elements) from the user and used to calculate the sum of numbers in one-dimensional array.
Calculate the sum of array elements – get input from the user
import java.util.Scanner;
class Array_Sum1{
public static void main (String args[]){
Scanner sc=new Scanner(System.in);
int[] marks =new int[10];
//diclaration and creation array
int sum=0;//initializing sum
System.out.println("Enter the array elements");
for(int i=0; i<10; i++){
marks[i]=sc.nextInt();//get input from user
}
for(int i=0; i<10; i++){
sum=sum+marks[count];//find sum using loop
}
System.out.println("Sum of array elements:"+sum);
}//display the sum on screen
}
When the above code is compiled and executed, it produces the following results
Enter the array elements 12 23 34 45 56 67 78 89 90 98 Sumof array elements: 592
Program 3
Calculate the sum of array elements Using Advanced for loop
This program calculate sum of array elements using enhanced for loop
class Arraysum2{
public static void main (String args[]){
int[] array={23,45,67,54,87}; //diclaration and creation
int sum=0;
for(int count:array){
sum=sum+count;
}
System.out.println("sum of array elements is:"+sum);
}
}
When the above code is compiled and executed, it produces the following results
the sum of array elements is: 276
Program 4
Calculate the sum of array elements -takes input from the user
This program take input from user and calculate sum of array elements using enhanced for loop
import java.util.Scanner;
class Enhanced_For_Sum{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
int[] marks=new int[5];//array declaration
int sum=0;//variable declaration
System.out.print("Enter the array elements: \n");
for(int count=0; count<5; count++){ //loop iterates for take input from user
marks[count]=scan.nextInt();//take input element from user
}
for(int count:marks){ //loop for calculates sum
sum=sum+count;
}
System.out.println("sum of array elements is:"+sum);
}//display result on the screen
}
When the above code is compiled and executed, it produces the following results
Enter the array elements: 54 46 56 44 50 sum of array elements is:250
