[Solved] Can someone help me for convert this c# recursive function to java [closed]

by 


public final boolean ParantezKontrol(String input)
{
    return ParantezKontrol(input, 0);
}

//Java does not support optional parameters. So you can overload this method
//ORIGINAL public bool ParantezKontrol(string input, int numOpen = 0)
public final boolean ParantezKontrol(String input, int numOpen)
{
        if (numOpen < 0)
        {
            return false;
        }
        if (isNullOrEmpty(input))
        {
            return numOpen == 0;
        }

        char c = input.charAt(0);
        String rest = input.substring(1);
        if (c == '(')
        {
            return ParantezKontrol(rest, numOpen + 1);
        }
        else if (c == ')')
        {
            return ParantezKontrol(rest, numOpen - 1);
        }
        else
        {
            return ParantezKontrol(rest, numOpen);
        }
}

isNullOrEmpty and substring methods are not present in Java, So Write your own methods:

public static boolean isNullOrEmpty(String string)
{
    return string == null || string.length() == 0;
}
public static String substring(String string, int start, int length)
{
    if (length < 0)
        throw new IndexOutOfBoundsException("Parameter length cannot be negative.");

    return string.substring(start, start + length);
}
