Question

Given a scanner reference variable named input that has been associated with an input source consisting of a sequence of strings and two int variables, count and longest, write the code necessary to examine all the strings in the input source and determine how long the longest string (or strings are). that value should be assigned to longest; the number of strings that are of that length should be assigned to count.

Answer 1

The code that examines all the strings in the input source and determines how long the longest string (or strings are) is the following:

total = 0; % initial value is zero, in every while loop it will be incremented

while(input.hasNextInt()){

total += input.nextInt( );

}

Answer 2

Answer:

int count = 0;  //int variables

int longest =0;  // int variables

Scanner input = new Scanner(System.in); // given input is reference variable

String str= new String();  // creating object of sting class

while (input.hasNext()) // taking the input by using scanner reference

{

str= input.next();  // taking input in string

if (str.length() == longest) // checking condition

++count;  // increment the count

else

if (Str.length() > longest) // if string is greater then longest

{

longest = str.length(); // calculating length

count = 1;  // assign count to 1

}

}

Explanation:

Following are the description of the code :

• Declared a two variable count and longest of  int type.
• Create a object of String class i.e 'str".
• Taking input in the string by using scanner reference i.e "input".
• Finally checking the condition of if and else block and calculating the length of string and assign into longest variable.
