Write ac program to reverse the words in a sentence in place
I have used StringBuilder for concatenating String here. One question candidate should definitely ask is, what constitutes a word here? Further Learning.
Program to reverse a string in c
Arrays; import java. You will get the following output. I have used StringBuilder for concatenating String here. Second method is even more easier, instead of using Collections. Here is the second snapshot of the sample run: Let's take another sample run where user has provided any string that contains spaces say codes cracker dot com. This will reverse your ArrayList and you will have all the words in reverse order, now all you need to do is concatenate multiple String by iterating over ArrayList. This is the first snapshot of the sample run: Provide any string say codescracker and press enter key to see the string in reverse order. C Print String in Reverse Order Here is the program that will ask from the user to enter any string at run-time and then will print the string in reverse order without actually reversing the string. It will also handle words separated by multiple spaces, so you don't need to worry. SQL, database, networking and Java. That's all about how to reverse words in a String sentence in Java. Also asking a question not only fill the gaps in requirement but also help you to make an impression. Once you got the array, you can create an ArrayList from array and then you are eligible to use Collections. So its also good to prepare a solution based upon pure programming logic.
It will also handle words separated by multiple spaces, so you don't need to worry. Always remember "Devil is in detail".
For the purpose of this program, the word is nothing but a sequence of non-space characters. Never assume you know everything, even if its looks a simple problem.
Now, if you are a good programmer then you should have some right questions for the programmer.
Print a string in reverse order in c
Never assume you know everything, even if its looks a simple problem. It's good to practice this kind of coding problems both to learn Java and to improve your programming and coding skill. This is the first snapshot of the sample run: Provide any string say codescracker and press enter key to see the string in reverse order. If you know how to reverse array in Java , then you have an advantage because String is nothing but a character array, but tricky part is you don't need to reverse array but to reverse words. In this code example, I have shown two ways to reverse words in a String, first one is using, Java's regular expression support to split the string on spaces and then using reverse method of Collections utility class. It's simple and straight forward. Your program must produce a String contains the word in reverse order , for example if given input is "Java is Great" then your program should return "Great is Java". Once you got the array, you can create an ArrayList from array and then you are eligible to use Collections.
One more important question for Interviewer is about spacing between words, is it possible to have multiple spaces between two words?
This way, you even don't need to convert your String array to ArrayList of String.
