To check if we succeed in our goal, we can read theinputStreamusingread(), and convert everybyteto achar. This will return our original string. importjava.io.ByteArrayInputStream;importjava.io.IOException;importjava.io.InputStream;importjava.nio.charset.StandardCharsets;publicclassMain{publicstat...
12. Method used to take a string as input in Java?next() nextLine() Both A. and B. None of theseAnswer: B) Both A. and B.Explanation:The next() method can read the input only till the space. It can't read two words separated by space, while the nextLine() reads input ...
To convert a given string into the InputStream, Java provides ByteArrayInputStream class that is used along with a built method named getBytes(). While displaying a long input string, we are sometimes required to process them in smaller units. At that time, converting that string into the ...
Java’s Scanner class can also be used to convert an InputStream to a String. We can create a new Scanner object and use itsuseDelimiter()method to specify the delimiter as"\A". This causes the Scanner to read the entire input stream until the end, resulting in a single token that rep...
Alternatively, we can use theBufferedReader.lines()method [added in Java 8] to get theStreamof lines and process the content as needed. InputStreamin=newFileInputStream(newFile("C:/temp/test.txt"));StringnewLine=System.getProperty("line.separator");StringfileContent;try(Stream<String>lines=...

* Convert input string to UTF-8, copies into buffer (at given offset). * Returns number of bytes in the string. * *Java's internal UTF8 conversion is very, very slow. * This is, rather amazingly, 8x faster than the to-string method. ...

To split the input, StringTokenizer is 4X faster than string.split(). 参考:https://www.cpe.ku.ac.th/~jim/java-io.html 所以,即使 JDK 不鼓励使用它了,但它并未被废除,并且性能还这么强,在一些对性能比较敏感的系统中,或者对性能比较有要求的编程竞赛中,StringTokenizer 就能发挥重要作用。 所以,大胆...
