How to remove HTML Special Characters and replace the Special Character with the resp

[pavanragi]

Hii
I have a requirement to remove HTML Special Characters and replace the Special Character with the respective value from a String in j2me java........

For Example:

I have a String like this:

Federation of A Chambers of Commerce & Industry Awards for the year 2010-11. Speaking on the occasion,
He said, "About 54 percent of the population is youth aged below 25 years. We have to use their energy and
intelligence for development of the state as well as the country.The youth trained will also be absorbed by
companies.’"

I want to replace " with "
I want to replace &nbsp with space
I want to replace ’ with ’
I want to replace & with &

Like this etc......................

The text is dynamic that i will get From different Links

Like this etc...................... Any Help........

Hello,
It is possible. You need a method to replace a string with another string. Using String.indexOf and String.substring it is possible to create such.

Sample which would replace " with "

String text = ""Single quote";
int index = text.indexOf(""");
if (index != -1) {
   text = text.substring(0, index) + "\"" + text.substring(index + """.length());
}

Hi pavanragi,

Would something like this cover your case?

protected void startApp() {
		String in = "Federation of A Chambers of Commerce & Industry Awards for the year 2010-11. Speaking on the occasion," +
                      "He said, "About 54 percent of the population is youth aged below 25 years. We have to use their energy and" +
                      "intelligence for development of the state as well as the country.The youth trained will also be absorbed by" +
                      "companies.’" ";
		
		String out = replace(in, """, "\"");
		out = replace(out, "&nbsp", " ");
		out = replace(out, "’", "’");
		out = replace(out, "&", "&");
		
		
		System.out.println(out);
	
	}
	
	protected String replace(String s, String from, String to) {
		int i = s.indexOf(from);
                //if the special character is found at least once in the text
		if(i >= 0) {
                        //until all instances of the special character are replaced
			while(i >= 0) {
                                //if the special character is found at the beginning of the text
				if(i == 0)
					s = to + s.substring(1, s.length());
				//if the special character is found after the beginning of the text
                                else
					s = s.substring(0, i) + to + s.substring(i + from.length(), s.length());
        		        //look for new replacements from the current cursor position until the end of the text
				i = s.indexOf(from, i + from.length());
			}
		}
		
		return s;
    }

Hi pavanragi,

The attached code, includes a while loop that identifies all instances of a given special character and replaces them all with a single call to the replace() method. I have added some comments in the code.
