Java Program to reverse tOGGLE each word in String

We can reverse tOGGLE each word of a string by the help of reverse(), split(), toLowerCase(), toUpperCase() and substring() methods. By the help of split(“\s”) method, we can get all words in an array. To get the first character, we can use substring() or charAt() method.

Let’s see the example to reverse tOGGLE each word in a string.

File: StringFormatter.java

 public class StringFormatter { public static String reverseToggle(String str){ String words[]=str.split(“\s”); String reverseToggle=””; for(String w:words){ StringBuilder sb=new StringBuilder(w); sb.reverse(); String first=sb.substring(0,1); String afterfirst=sb.substring(1); reverseToggle+=first.toLowerCase()+afterfirst.toUpperCase()+” “; } return reverseToggle.trim(); } } 

File: TestStringFormatter.java

 public class TestStringFormatter { public static void main(String[] args) { System.out.println(StringFormatter.reverseToggle(“my name is khan”)); System.out.println(StringFormatter.reverseToggle(“I am Tutor Aspire Team”)); } }
