All Non-repeating character in a given string is:r g q u e o

Program in Java

Here is the source code of the Java Program to Find all non repeated characters in a string.

Code:

import java.util.Scanner;

public class AllNonRepeatingCharacter {

public static void main(String[] args) {

Scanner cs=new Scanner(System.in);

String str;

System.out.println("Enter your String:");

str=cs.nextLine();

int i;

    int arr[]=new int[256];

    for(i=0;i<str.length();i++)

    {

        if(str.charAt(i)!=' ')

           arr[str.charAt(i)]++;

    }

    char ch=' ';

    System.out.print("All Non-repeating character in a given string is:");

   for(i=0;i<str.length();i++)

    {

        if(arr[str.charAt(i)]==1){

            ch=str.charAt(i);

            System.out.print(ch+" ");

        }

    }

cs.close();

}

}

Input/Output:

Enter your String:
