Given a scanner reference variable named input that has been associated with an input source consisting of a sequence of integers and an int variable named total, write the code necessary to add all the integers in the input source and place their sum into total.

The answer is total = 0;while(input.hasNextInt()){total += input.nextInt( );}   Given a scanner reference variable named input that has been associated with an input source consisting of a sequence of integers and an int variable named total, The code necessary to add all the integers in the input source and place their sum into total is :                                                  total = 0;while(input.hasNextInt()){total += input.nextInt( );}   

Following are the code written in the Java Programming Language.

total = 0;   //set integer type variable and initialize to 0

while(input.hasNextInt()){   //set the while loop

total += input.nextInt( );  //code is here

}

Explanation:

Here, in the following code create the reference scanner class object i.e., "input".

Then, we set integer data type variable "total" and initialize 0 in it. then, we set the while loop and pass the following condition "input.hasNextInt()". Then, we add all integer values and store their sum in the variable "total".
