reset(): This method is available in the java.io.StringReader class of Java.
Syntax:
void java.io.StringReader.reset() throws IOException
This method resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.
Parameters: NA
Returns: NA
Throws:
1. IOException - If an I/O error occurs
Approach 1: When no exception
Java
import java.io.IOException;import java.io.StringReader;public class StringReaderreset {public static void main(String[] args) {String s = "HELLO JAVA";StringReader stringReader = new StringReader(s);try {stringReader.reset();System.out.println("Successfully reset");} catch (IOException e1) {System.out.println("IOException occurs");}}}
Output:
Successfully reset
Approach 2: IOException
Java
import java.io.IOException;import java.io.StringReader;public class StringReaderreset {public static void main(String[] args) {String s = "HELLO JAVA";StringReader stringReader = new StringReader(s);stringReader.close();try {stringReader.reset();System.out.println("Successfully reset");} catch (IOException e1) {System.out.println("IOException occurs");}}}
Output:
IOException occurs
Some other methods of StringReader
close(): This method closes the stream and releases any system resources associated with it.
mark(int): This method marks the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.
markSupported(): This method tells whether this stream supports the mark() operation, which it does.
read(): This method reads a single character.
read(char[], int, int): This method reads characters into a portion of an array.
ready(): This method tells whether this stream is ready to be read.
reset(): This method resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.
skip(long): This method skips the specified number of characters in the stream.
StringReader(String): This method creates a new string reader.
