Question

WAP in java to take a sentence from the user and remove the extra spaces
Example :-
Output :My name is Khan
Input : My name is Khan

Answer 1

Answer:

As the program stated we need to remove all the spaces.

The spaces is called here the white space. Now to remove those white spaces in JAVA we have a string function named 'trim' which will remove all the extra white spaces from a string and return the moderate one.

Here we have use another string function 'replaceAll' which will return any string after having its  particular operation.

class removeSpace {  

 public static void main(String args[]) {  

   String s = "My  name  is  Khan   ";  

   System.out.println(s.replaceAll("\\s+"," ").trim());  

 }  

}
