Write a java program to reverse each word in string?
StringBuffer class of the java.lang package provides reverse() method. This method returns a reverse sequence of the characters in the current String. Using this method you can reverse a string in Java.
To reverse each word in a string you need to split the string, store it in an array of strings and reverse each word using the reverse() method of the StringBuffer class.
Example
import java.lang.*;
public class StringBufferDemo {
public static void main(String[] args) {
StringBuffer buff = new StringBuffer("tutorials point");
System.out.println("buffer = " + buff);
// reverse characters of the buffer and prints it
System.out.println("reverse = " + buff.reverse());
// reverse of the buffer is equivalent to the actual buffer
buff = new StringBuffer("malyalam");
System.out.println("buffer = " + buff);
// reverse characters of the buffer and prints it
System.out.println("reverse = " + buff.reverse());
}
}Output
buffer = tutorials point reverse = tniop slairotut buffer = malyalam reverse = malaylam
