This is what I currently have been trying to get an output like this:
input: this is a sentence
output: a is this sentence
import java.util.Scanner;
Scanner input = new Scanner(System.in);
System.out.print("Enter a sentance:");
String text = input.nextLine();
String[] words = text.split("");
String temp;
for (int i = 0; i < words.length; i++) {
for (int j = 0; j < (words.length - 1); j++) {
if (words[j].compareTo(words[j + 1]) < 0) {
temp = words[j];
words[j] = words[j + 1];
words[j + 1] = temp;
}
}
System.out.print(words[i]);
}
}
}
If anyone could help that would be great!
You may convert the input to a list and then sort using a lambda:
Scanner input = new Scanner(System.in);
System.out.print("Enter a sentence:");
String text = input.nextLine();
List<String> words = Arrays.asList(text.split(" "));
words.sort(Comparator.comparingInt(String::length));
System.out.println(String.join(" ", words));
This prints (for input this is a sentence):
a is this sentence
@Test
public void testSort() {
Assertions.assertEquals("a is this sentence", sort("this is a sentence"));
}
private String sort(String sentence) {
return Arrays.stream(sentence.split(" "))
.sorted(Comparator.comparingInt(String::length))
.collect(Collectors.joining(" "));
}
// split words by space then sort by length and join words again by space.
