Java scanner move cursor to end of line

Forum: Beginning Java. Scanner moving onto next line. Anthony Noack. I'm taking a programming class at my school and have an assignment to create a bank balance calculator. I have no problem doing so and have already completed the math however I want to fix my output.

Currently I have: System. Campbell Ritchie. I don't think you can instruct the terminal cursor to move to a particular location. If you use nextLine, it reads from the current location to the next time the Enter key is pressed. You can try System. Delay printing the output until after you have got all the input.

Beware of nextLine after nextSomethingElse. And welcome to the Ranch. Les Morgan. I like When you use System.

When you do console based apps in Javait is much easier to do the advance to the next line and use combinations of print and println to get the look you want for the new line. Out on HF and heard nobody, but didn't call CQ? Nobody heard you either. Thats unfortunate but thank you for the response', I will probsbly create a 4th colum for input it will just be on multiple lines.

Trying to create OO based bank app. Suppressing proceeding statements after if statement fails.I must do it this way because the calling class will only give me a Scanner object. You probably already know if you had the File object, you could recreate the Scanner and that would reset the pointer to the beginning of the file.

But since you don't have that, you need to rethink your loops. Can you think of a way to combine both checking for words and checking for the end of a line inside a single loop?

You could read a whole line into a String and then create a Scanner to read individual words from that String. To rewind back to the beginning of the String, create a new Scanner with that String again.

Yep, NormR1, that's how I finally figured it out. An extraodrinarily lame workaround, but it worked on paper. Wiley Plus' labrat choked on it tho. If I could write a custom data scrubbing class, ya kramerd I'd use the File object What I'd like to eventually do is write a generic input data scrubbing class for any data stream - I wonder if something like that has already been written?

Because it consumes the new-line character that was not consumed by nextInt.

Java.util.Scanner.nextLine() Method

Notes: — This is a logic error, since every method work as intended, but they are not used correctly. While nextLine reads the String and consumes the new-line character.

According to Java Docs : … This method returns the rest of the current line, excluding any line separator at the end. The position is set to the beginning of the next line. The second way is using nextLine instead of nextInt to read the number. But since nextLine returns a Stringwe will have to convert this String to a integer.

We can use Integer. Using the second way, we can receive an Exception from the Integer. To handle this Exception, you will have to use a try-catch block. I mean, what you say is valuable and all.

So, how to solve this? There are two simple solutions: Add a nextLine extra, between the nextInt and nextLine. This extra nextLine will consume the new-line character, so the following nextLine will work fine.The nextLine method of Scanner class is used to take a string from the user.

It is defined in java. Scanner class. The nextLine method reads the text until the end of the line. After reading the line, it throws the cursor to the next line. The method returns the line that was skipped.

It does not accept any parameter. When it does not find any line, then it throws NoSuchElementException. It also throws IllegalStateException if the scanner is closed. Java next method can read the input before the space id found. It cannot read two words separated by space. It retains the cursor in the same line after reading the input.

The method returns the next complete token from this scanner. It throws NoSuchElementException if no more tokens are available. We can see that whatever we write after Java is skipped by the method and read only the word Java. JavaTpoint offers too many high quality services. Mail us on hr javatpoint.

It only takes a minute to sign up. I'm in very early stages of learning some Java coding. I'm asking for this review because, although the code below works, I'd like to know if it's an ugly way of achieving it. What I want the code to do is take input from Scanner and reprint it, except if the input is empty, ie, just hit the return key, in which case the Scanner should close and the program end. Use nice indentation using 4 spaces. This improves the readability a lot. See the official guidelines on indentation here.

Basically every time you open a new curly brace you should start a new indentation depth. See code sample below. Use braces around all kinds of blocks, e. Also, for Java it is the official convention to place the braces like this:. You can use a trick to assign the value of the scanner input to a variable inside the while condition and then use the String's isEmpty function to check if the input was empty. This way you can spare the boolean variable indicating whether something was read:.

Use try to create instances of Types that implement java. AutoCloseable to make sure they are automatically closed when the block ends Note this only works with Java 7 or newer :. See here for reference. Is this really still a Todo? Imagine yourself coming back to this code six months from now.
