[masaka]

Hello , How To count the occurnces of astring in another string I try This Code but the result is wrong help please

Code:

    {
        System.out.println("Enter Two stings ");
        System.out.println();
        String str1 = console.nextLine();
        String str2 = console.nextLine();
       print (count (str1,str2 ));  
    }       
    public static int  count (String x, String y)
    {
    int num = x.replaceAll(x ,y).length();
    return(num);
    }        
    public static void  print (int b)
    {
    System.out.println("The Number of occrrunces is " +b);
    }
}

Just to confirm,

Can you show the example inputs and an output?

Here is a classical implementation:

Code:

package javaforums;

public class StringCount
{
    public static void main(String[] args)
    {
        String source = "String having a lot of instances of the substring in";
        String query = "in";
        int occ = 0;

        int pos = source.indexOf(query);
        while (pos != -1)
        {
            System.out.println("Query string [" + query + "] found at index: " + pos);
            occ++;
            pos = source.indexOf(query, pos + query.length());
        }

        System.out.println("Query string [" + query + "] found: " + occ + " times");
    }
}

When you run it, it will display:

Code:

Query string [in] found at index: 3
Query string [in] found at index: 10
Query string [in] found at index: 23
Query string [in] found at index: 46
Query string [in] found at index: 50
Query string [in] found: 5 times

You can adapt it to your requirements so you read the source and query strings from the console. Enjoy.
