Introduction
This program helps to remove duplicate character from the input string.
Like we passed String as “Dharmendra” and a is duplicate in the string so result will be “Dharmend“.
Flowchart
Please find sample flowchart diagram for this program as given below –
Program(Code) Using Java Language
package com.kw.sample;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class KWRemoveDuplicateCharExample {
public static void main(String[] args) throws IOException {
// Instantiate BufferedReader object to take input string
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print(“Enter any word : “);
String str = br.readLine();
int len = str.length();
char ch;
String result = “”;
// Iterate String
for (int i = 0; i < len; i++) {
// Pick character
ch = str.charAt(i);
if (ch != ‘ ‘) {
result = result + ch;
}
str = str.replace(ch, ‘ ‘);
}
System.out.println(” String after Duplicate :” + result);
}
}
Output
Scenario 1:
Enter any word : Dharmendra
String after Duplicate :Dharmend
Scenario 2:
Enter any word : My Name is Dharmendra!
String after Duplicate :MyNameisDhrnd!
