Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter a sentence: ");
String sentence = in.nextLine();
String[] words = sentence.split("\\s");
for(String s : words)
System.out.println(s + " -> " + s.length());
}
}
Explanation:
Ask the user to enter a sentence
Get each word in the sentence using split method and put them in words array
Loop through the words. Print each word and number of characters they have using the length method in required format

Answer:
result = 0
i = lo
while i <= hi:
result = result + i
i += 1
Explanation:
Initialize the <em>result</em> as 0 to hold the summation value.
Since we are asked not to change the value of <em>lo</em> and <em>hi</em>, our loop control variable is <em>i</em> and initially it starts from <em>lo.</em>
Since we are asked to add the number from <em>lo</em> to <em>hi, </em>while loop condition checks it.
While the condition satisfies (during each iteration), the value of <em>i</em> is added to the result and the value of <em>i</em> is incremented by one.
Answer:
The answer to this question is option "d".
Explanation:
In the given question option d is correct because variable-length argument is a new feature in J2SE 5.0 which stands for java 2 standard edition and 5.0 is the version name. It is the variable-length argument lists. A coder can create functions that uses a function to receive several parameter that is not specified. An argument type followed by an ellipsis(...) in the parameter list of a method means that a fixed number of arguments of that particular type is obtained by the method. and other options are not correct that can be given as:
- In option a, we do not need to use the string the variable-length argument list. That's why it is wrong.
- The option b and c are all wrong because in the last parameter the variable-length argument list is used.
That's why the answer to this question is the option "d".
