EXERCISE 93 : Create and use arrays

Objectives

At the end of this exercise you shall be able to
• know about single dimensional and two dimensional arrays and its use in Java
• develop Java programs using single dimensional and two dimensional arrays.

Requirements

Tools/Materials
• PC/Laptop with Windows OS
• JDK Software
• Text editor (Visual studio / Sublime / Note pad)

Procedure

1 Single Dimensional Arrays
TASK 1: Method1: Sum of Array Elements
// Sum of Array elements

public class SumOfArray {
public static void main(String[] args) {
// Declare and initialize an array
int[] numbers = {1, 2, 3, 4, 5};

System.out.print(“Array elements are: “ );
// Initialize sum variable
int sum = 0;

// Iterate through the array and add each element to sum
for (int i = 0; i < numbers.length; i++) {

System.out.print(numbers[i]+” “);
sum += numbers[i];
}
// Go to the next line

System.out.println();
// Print the sum
System.out.println(“Sum of array elements: “ + sum);
}
}
