To remove all duplicate words from a given sentence, the Java code is as follows −
Example
import java.util.Arrays; import java.util.stream.Collectors; public class Demo{ public static void main(String[] args){ String my_str = "This is a is sample a sample only."; my_str = Arrays.stream(my_str.split("\\s+")).distinct().collect(Collectors.joining(" ")); System.out.println(my_str); } }
Output
This is a sample only.
A class named Demo contains the main function. In this function, a String object is defined. It is split based on the spaces and only distinct words of the string are joined together using space as a separator and displayed on the console.
