Write a Java Program To Reverse The String With Preserving The Position Of Spaces ?

Write a Java Program to reverse string with preserving the spaces.For Example suppose we have String "I Love Java" then output must be "a vaJe voLI".

Example :

public class ReverseStringWithPreservingWhiteSpace {
 
 public static void getReverse(String str){
  
  char[] resultArray = new char[str.length()];
  
  for(int i=0;i<str.length();i++){
   if(str.charAt(i) == ' '){
    resultArray[i] = ' ';
   }
  }
  int n = resultArray.length - 1;
  
  for(int i=0;i<str.length();i++){
   if(str.charAt(i) != ' '){
    if(resultArray[n] == ' '){
     n--;
    }
    resultArray[n] = str.charAt(i);
    n--;
   }
  }
  System.out.println(str+" :- "+String.valueOf(resultArray));
 }
 public static void main(String[] args) {
  getReverse("Java is strongly Typed Language");
  getReverse("I Love Java");
 }
}

Output :

Java is strongly Typed Language :- egau gn aLdepyTy lgnor tssiavaJ

I Love Java :- a vaJe voLI
