Reverse words in a String
This program reverses every word of a string and display the reversed string as an output. For example, if we input a string as "Reverse the word of this string" then the output of the program would be: "esrever eht drow fo siht gnirts".
public class Example
{
public void reverseWordInMyString(String str)
{
/* The split() method of String class splits
* a string in several strings based on the
* delimiter passed as an argument to it
*/
String[] words = str.split(" ");
String reversedString = "";
for (int i = 0; i < words.length; i++)
{
String word = words[i];
String reverseWord = "";
for (int j = word.length()-1; j >= 0; j--)
{
/* The charAt() function returns the character
* at the given position in a string
*/
reverseWord = reverseWord + word.charAt(j);
}
reversedString = reversedString + reverseWord + " ";
}
System.out.println(str);
System.out.println(reversedString);
}
public static void main(String[] args)
{
Example obj = new Example();
obj.reverseWordInMyString("This is an easy Java Program");
}
}
Output
This is an easy Java Program
