Java Program to print the sum of all the items of the array

In this program, we need to calculate the sum of all the elements of an array. This can be solved by looping through the array and add the value of the element in each iteration to variable sum.

Sum of all elements of an array is 1 + 2 + 3 + 4 + 5 = 15.

Algorithm

• STEP 1: START
• STEP 2: INITIALIZE arr[] = {1, 2, 3, 4, 5}
• STEP 3: SET sum = 0
• STEP 4: REPEAT STEP 5 UNTIL i<arr.length
              //for(i=0; i< arr.length; i++)
• STEP 5: sum = sum + arr[i]
• STEP 6: PRINT "Sum of all the elements of an array:"
• STEP 7: PRINT sum
• STEP 8: END

Program:

Output:

Sum of all the elements of an array: 15
