How to remove the white spaces?
Following example demonstrates how to remove the white spaces with the help matcher.replaceAll(stringname) method of Util.regex.Pattern class.
import java.util.regex.Matcher; import java.util.regex.Pattern; public class Main { public static void main(String[] argv) throws Exception { String ExString = "This is a Java program. This is another Java Program."; String result=removeDuplicateWhitespace(ExString); System.out.println(result); } public static CharSequence removeDuplicateWhitespace(CharSequence inputStr) { String patternStr = "\\s+"; String replaceStr = " "; Pattern pattern = Pattern.compile(patternStr); Matcher matcher = pattern.matcher(inputStr); return matcher.replaceAll(replaceStr); } } |
The above code sample will produce the following result.
