Reverse String Method 1: 1. The user will input the string to be reversed. 2. First we will convert String to character array by using the built in java String class method toCharArray(). 3. Then , we will scan the string from end to start, and print the character one by one. Reverse String Method 2: 1. In the second method , we will use the built in reverse() method of the StringBuilder class ,. Note : String class does not have reverse() method . So we need to convert the input string to StringBuilder , which is achieved by using the append method of the StringBuilder. 2. After that print out the characters of the reversed string by scanning from the first till the last index. Reverse String Method 3: 1. Convert the input string into character array by using the toCharArray() built in method of the String Class . 2. In this method we will scan the character array from both sides , that is from the start index (left) as well as from last index(right) simultaneously. 3. Set the left index equal to 0 and right index equal to the length of the string -1. 4. Swap the characters of the start index scanning with the last index scanning one by one .After that increase the left index by 1 (left++) and decrease the right by 1 i.e (right--) to move on to the next characters in the character array . 5. Continue till left is less than or equal to the right . Reverse String Method 4: 1. Convert the input string into the character array by using toCharArray() built in method. reverse a string in java with example 2. Then add the characters of the array into the LinkedList object . We used LinkedList because it maintains the insertion order of the input values. 3. Java also has built in reverse() method for the Collections class . Since Collections class reverse() method takes a list object , to reverse the list , we will pass the LinkedList object which is a type of list of characters. 4. We will create the ListIterator object by using the listIterator() method on the LinkedList object. ListIterator object is used to iterate over the list. 5. ListIterator object will help us to iterate over the reversed list and print it one by one to the output screen. Reverse String Method 5 : 1. The last method is converting string into bytes . getBytes() method is used to convert the input string into bytes[]. 2. Then we will create a temporary byte[] of length equal to the length of the input string. 3. We will store the bytes(which we get by using getBytes() method) in reverse order into the temporary byte[] . read less
