The deleteWhitespace() method of the StringUtils class of the Commons LangS library removes all whitespace characters from a String. This is demonstrated by the RemoveAllWhitespaceTest class: RemoveAllWhitespaceTest.javapackage test; import java.io.IOException; import org.apache.commons.lang.StringUtils; public class RemoveAllWhitespaceTest { public static void main(String[] args) throws IOException { String str1 = "\n\tThis is my string \n \r\n !"; System.out.println("Original String:"); System.out.println("[" + str1 + "]"); System.out.println("Whitespace Removed:"); System.out.println("[" + StringUtils.deleteWhitespace(str1) + "]"); System.out.println(); String str2 = " , . ! This is another string \t , ."; System.out.println("Original String:"); System.out.println("[" + str2 + "]"); System.out.println("Whitespace Removed:"); System.out.println("[" + StringUtils.deleteWhitespace(str2) + "]"); } } The output of RemoveAllWhitespaceTest's execution is shown here: ResultsOriginal String: [ This is my string !] Whitespace Removed: [Thisismystring!] Original String: [ , . ! This is another string , .] Whitespace Removed: [,.!Thisisanotherstring,.] |
