Hi
I want to match a pattern in a string. Unfortunately I have nt been able to find any examples which show how to use the stringpattern class. Can anyone plz show give brief description of how to match a pattern in a string. Thnk u in advance

What are you trying to do - match to verify the String or match to provide some processing option?

Example if I have a string1 harajukuktcgh. And the user enters string2 ajuku. I want to check if string1 contains string2 pattern.

This may helps you:

       public boolean isEqualToString(String source, String pattern)
	{    
	    if (source == null || pattern==null)
	    	return false;
	    if(source.length()==0||pattern.length()==0||source.length()<pattern.length())
	    	return false;
	    
	    int index=0;
	    while(index<source.length())
	    {
	    	if(source.charAt(index)==pattern.charAt(0))
	    	{
	    		String str=source.substring(index,index+pattern.length());
	    		if(str.equals(pattern))//If you don't want case sensitive then use "str.equalsIgnoreCase(pattern)"
	    		{
	    			System.out.println("=========Equal String ==============: "+str);
	    			return true;
	    		}
	    	}
	    	index++;
	    }
	    return false;
	}
	
//Example:  boolean isContainsString=isEqualToString("Ali shaik ali", "ali");

Try this and let me know.

First of all thanks for giving this type of suggesstion to find the solution in "less coding". 

As you mentioned, we can get by using StringMatch class

//Example: boolean isMatch=hasString("Ali shaik ali", "ali");

public boolean hasString(String name, String pattern)
{   		
	// new StringMatch(patternToMatch, caseSensitivity, spaceDelimitsNewPattern);
	StringMatch match=new StringMatch(pattern,true,true);
	if(match.indexOf(name)!=-1)
	{
		System.out.println("=======String: "+name+"=======has====== "+pattern+" : "+match.numStringsInPattern()+" times");
		return true;
	}
	else
		return false;
}

 Try this and Let me know.
