Java Program to replace a word with asterisks in a sentence
To replace a word with asterisks in a sentence, the Java program is as follows −
Example
public class Demo{
static String replace_word(String sentence, String pattern){
String[] word_list = sentence.split("\s+");
String my_result = "";
String asterisk_val = "";
for (int i = 0; i < pattern.length(); i++)
asterisk_val += '*';
int my_index = 0;
for (String i : word_list){
if (i.compareTo(pattern) == 0)
word_list[my_index] = asterisk_val;
my_index++;
}
for (String i : word_list)
my_result += i + ' ';
return my_result;
}
public static void main(String[] args){
String sentence = "This is a sample only, the sky is blue, water is transparent ";
String pattern = "sample";
System.out.println(replace_word(sentence, pattern));
}
}Output
This is a ****** only, the sky is blue, water is transparent
A class named Demo contains a function named ‘replace_word’ that takes the sentence and the pattern as parameters. A sentence is split and stored in a string array. An empty string is defined, and the pattern is iterated over, based on its length.
An asterisk value is defined as ‘*’ and for every character in the sentence, the character is compared to the pattern and a specific occurrence is replaced with the asterisk symbol. The final string is displayed on the console.
