Question

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.

Answer 1

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( );}   

Answer 2

Answer:

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".
