highest occurrence of char in a string java code example
Example: c# + max char frequency in string
public static void Main(string[] args)
{
CharCounter("This is a neat day for Things about Coding9999");
}
public static void CharCounter(string str)
{
string strValidated = "";
str = str.Replace(" ", "");
if (Regex.IsMatch(str, @"^[A-Za-z0-9]+$")) strValidated = str;
else throw new FormatException("--------> Only Apha Numeric values allowed");
Dictionary<char, int> dict = new Dictionary<char, int>();
foreach (char c in strValidated)
{
if (dict.ContainsKey(c)) dict[c] = dict[c] + 1;
else dict.Add(c, 1);
}
var ordered = dict.OrderByDescending(x => x.Value)
.ToDictionary(d => d.Key, d => d.Value);
var result = ordered.Take(1)
.ToDictionary(d => d.Key, d => d.Value);
foreach (var item in result.Keys)
{
Console.WriteLine($"Key= {item} : Value= {result[item]}");
}
}
