java.io.BufferedInputStream close()
Description
On this document we will be showing a java example on how to use the close() method of BufferedInputStream Class. This method closes this input stream and releases any system resources associated with the stream. Once the stream has been closed, further read(), available(), reset(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.
Specified by:
- close in interface Closeable
- close in interface AutoCloseable
Overrides:
- close in class FilterInputStream
Throws:
- IOException – if an I/O error occurs.
Method Syntax
public void close()
throws IOException
Method Argument
| Data Type | Parameter | Description |
|---|---|---|
| N/A | N/A | N/A |
Method Returns
This method returns void.
Compatibility
Requires Java 1.0 and up
Java BufferedInputStream close() Example
Below is a java code demonstrates the use of close() method of BufferedInputStream class. The example presented might be simple however it shows the behaviour of the close().
package com.javatutorialhq.java.examples;
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
/*
* This example source code demonstrates the use of
* close() method of BufferedInputStream class
*/
public class BufferedInputStreamCloseExample {
public static void main(String[] args) {
try {
// initialize an input stream which in this case
// we are intended to read a file thus
// FileInputStream object suits it best
FileInputStream fis = new FileInputStream("C:javatutorialhq"
+ "inputtest_file.txt");
// initialize BufferedInputStream object
BufferedInputStream bufferedStream = new BufferedInputStream(fis);
// wrap the stream to BufferedReader
BufferedReader br = new BufferedReader(new InputStreamReader(bufferedStream));
String value;
while((value=br.readLine())!=null){
System.out.print(value);
}
// close the BufferedInputStream
bufferedStream.close();
fis.close();
} catch (FileNotFoundException e) {
System.out.println("File does not exists");
} catch (IOException e) {
System.out.println("IOException occured");
}
}
}
