A String is nothing but a bunch of characters one after the other whereas a character has a size of only '1'
So converting a string into a char is not possible. what you can do is form a character based on only one element from the string.
Ex:
String name = "Rocky";
char xyz = name.charAt(0);
now the char xyz will have one character from the String.

Write a java program to reverse the words in a sentence in place?
This is actually an interesting request. A "sentence" in Java would normally be stored in a String object. However, you also requested an "in place" sort, which is not possible to do with a String.Strings are an immutable type, which means that once its value is set a String can never change. If you try to change it, Java will actually be making an entirely new String in the background.Given all of the above, the next best thing we can do is look at a reversal of a character array.// This method will accept a String, convert it to a char[], reverse the char[], then convert// it back into a String to return.public static String reverseSentence(final String sentence) {// Get the character array of sentencefinal char[] sentenceChars = sentence.toCharArray();// Iterate through the first half of the array and swap each character with its// "mirrored" counterpart - first and last swap, second and second-to-last swap...final int halfLength = sentenceChars.length / 2;for (int i = 0; i < halfLength; ++i) {final char temp = sentenceChars[i];sentenceChars[i] = sentenceChars[sentenceChars.length - i - 1];sentenceChars[sentenceChars.length - i - 1] = temp;}// Use String.valueOf(char[]) to recreate a Stringreturn String.valueOf(sentenceChars);}
