1. Using the IndexOf method:

public class Test11 
{

	private static int counter = 0;
	/**
	 * @param args
	 *
	/public static void main (string[] args) 
	{
		String str = "Sdss**&hgjhadhcasch & ^^ ";
		int i = stringnumbers (str);
		System.out.println (i);
	}
	
	public static int stringnumbers (String str)
	{
		if (str.indexof ("Java") ==-1)
		{return
			0;
		}
		else if (Str.indexof ("Java")!=-1)
		{
			counter++;
			Stringnumbers (Str.substring (Str.indexof ("Java") +4));
			return counter;
		}
		return 0;
	}
} 

2. If the substring is not a string with the same end and end, this can be done:

if (Str.indexof ("Java")!=-1)
	{
		string[] str1 = Str.split ("java");
		System.out.println (str1.length-1);
	}
	else 
	{
		System.out.println (0);
	}
