How to remove spaces from given string

Suppose you have a String str="hello my na me i s John". How will you remove the spaces between words.Its a very basic question asked in interview for freshers.

I have mentioned two ways to do the same problem one is using split function and another is using replace function.


Sample Program:-

/**  
  *   
  */  
 /**  
  * @author Dixit  
  *  
  */  
 public class RemoveSpaceInStrings {  
      /**  
       * @param args  
       */  
      public static void main(String[] args) {  
           String str="hello my na me i s John";  
           removeSpaceWithSplitFunction(str);  
           removeSpcaseWithoutSplitFunction(str);  
      }  
      private static void removeSpcaseWithoutSplitFunction(String str) {  
            System.out.println("removeSpcaseWithoutSplitFunction:Resulting String is:-" +str.replace(" ", ""));  
      }  
      private static void removeSpaceWithSplitFunction(String str) {  
         String result = "";  
         String strArray[] = str.split(" ");  
         for (int i = 0; i < strArray.length; i++) {  
           result = result + strArray[i];  
         }  
         System.out.println("removeSpaceWithSplitFunction:Resulting String is:-" + result);  
      }  
 }  

 Output  
 removeSpaceWithSplitFunction:Resulting String is:-hellomynameisJohn  
 removeSpcaseWithoutSplitFunction:Resulting String is:-hellomynameisJohn

Enjoy Programming :)
