StringReader close() in Java

close(): This method is available in the java.io.StringReader class of Java.

Syntax:

void java.io.StringReader.close()

This method closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(),ready(), mark(), or reset() invocations will throw an IOException.

Note: Closing a previously closed stream has no effect.

This method will block while there is another thread blocking the reader.

Parameters: NA

Returns: NA

Exceptions: NA

Approach

Java

import java.io.StringReader;

public class StringReaderclose {
    public static void main(String[] args) {

        String s = "HELLO JAVA";
        StringReader stringReader = new StringReader(s);

        stringReader.close();
        System.out.println("Successfully closed");
    }
}

Output:

Successfully closed
