Answer:
import java.util.Scanner;
public class num12 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the first String");
String word1 = in.nextLine();
System.out.println("Enter the second String");
String word2 = in.nextLine();
System.out.println("Enter the third String");
String word3 = in.nextLine();
//Remove all white spaces
String cword1 = word1.replace(" ","");
String cword2 = word2.replace(" ","");
String cword3 = word3.replace(" ","");
//Comparing the string by their lengths
if(cword1.length()>cword2.length()&&cword1.length()>cword3.length()){
System.out.println(word1+" Is the longest");
}
else if(cword2.length()>cword1.length()&&cword2.length()>cword3.length()){
System.out.println(word2+" Is the longest");
}
else{
System.out.println(cword3+" Is the longest");
}
}
}
Explanation:
Using Java Programming Language
Use the Scanner Class to obtain the String values from the user
Save them in different variables
Use the replace() method in java to remove white space from any of the string entered
Using if and else statements compare the lengths of the strings (word.length()) returns the length of the word.
Print out the word that is longest
NOTE I have compared three Strings, comparing two would have been more straigth forward
