Objectives:
- Write a Java program to find duplicate characters in the string and print the duplicate characters
- Write a program to find duplicate characters in String
Java Program:
[sourcecode lang="java"]
public class DuplicateCharacters {
public static void main(String args[]) {
String str = "NITIN";
int count = 0;
char input[] = str.toCharArray();
System.out.println("Duplicate Characters are:");
for (int i = 0; i < str.length(); i++) {
for (int j = i + 1; j < str.length(); j++) {
if (input[i] == input [j]) {
System.out.println(input[j]);
count++;
break;
}
}
}
}
}
[/sourcecode]
Output:
Duplicate Characters are: N I
