how to solve this without loops at all

/run

public class A{
    public static void main(String[] args){
        System.out.println(count("11abc11"));
        System.out.println(count("abc11x11x11"));
        System.out.println(count("111"));
    }

public static int count(String str)
{
if (str.length() < 2)
{
  return 0;
}
if (str.startsWith("11"))
{
  return 1 + count(str.substring(2));
}
  return count(str.substring(1));
}

}

public class A{
    public static void main(String[] args){
        System.out.println(count("11abc11"));
        System.out.println(count("abc11x11x11"));
        System.out.println(count("111"));
    }

public static int count(String str)
{
if (str.length() < 2)
{
  return 0;
}
if (str.startsWith("11"))
{
  return 1 + count(str.substring(2));
}
  return count(str.substring(1));
}

}

Sure something like this should work

public static int count(String str, String toCount)
{
if (str.length() < toCount.length())
{
  return 0;
}
if (str.startsWith(toCount))
{
  return 1 + count(str.substring(toCount.length()), toCount);
}
  return count(str.substring(1), toCount);
}

public static int count(String str, String toCount)
{
if (str.length() < toCount.length())
{
  return 0;
}
if (str.startsWith(toCount))
{
  return 1 + count(str.substring(toCount.length()), toCount);
}
  return count(str.substring(1), toCount);
}

Should work ig

How to check if a value coincide with any enum value?

So baiscally you have a string and want the enum value of it if there is one like this

String example = "Alejandra";

String example = "Alejandra";

and then you want the enum value of the string

Names name = Names.valueOf(example);

Names name = Names.valueOf(example);

there you go method

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
        return null;
    }
    else
    {
        System.out.println("Valid name");
        return name;
    }
}

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
        return null;
    }
    else
    {
        System.out.println("Valid name");
        return name;
    }
}

is also equal to

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
    }
    else
    {
        System.out.println("Valid name");
    }
    return name;
}

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
    }
    else
    {
        System.out.println("Valid name");
    }
    return name;
}
