Re: find the frequency of the character

You just count the number of times each one appears in the String. A simple web search would tell you that.

Re: find the frequency of the character

I sure he knows that, he just wants a code handout. Which he won't get.

If he posts his attempt at it, he might get help correcting it, but noone is going to do it for him.

Re: find the frequency of the character

Try this simple example:

Java Syntax (Toggle Plain Text)
String s = "asjdhk123uhmsmik,z!?";
for (int i=0;i<s.length();i++) {
  char ch = s.charAt(i);
  System.out.println(ch);
}
String s = "asjdhk123uhmsmik,z!?";
for (int i=0;i<s.length();i++) {
  char ch = s.charAt(i);
  System.out.println(ch);
}

Also you should always check the API to find more methods that could be useful. In this case, you should have looked the String API
