you are doing it wrong, you have first split the string using space as a delimiter using String.split() and populate the char array with charcters.
or even simpler just use String.charAt() in the loop to populate array like below:
String ini="Hi there";
char[] array=new char[ini.length()];
for(int count=0;count<array.length;count++){
array[count] = ini.charAt(count);
System.out.print(" "+array[count]);
}
or one liner would be
String ini="Hi there";
char[] array=ini.toCharArray();
