ByteArrayInputStream is a subclass of InputStream. True to the name, ByteArrayInputStream is used to read a byte array by way of a InputStream.
- AudioInputStream
- BufferedInputStream
- CheckedInputStream
- CipherInputStream
- DataInputStream
- DeflaterInputStream
- DigestInputStream
- FileInputStream
- FilterInputStream
- InflaterInputStream
- InputStream
- ObjectInputStream
- PipedInputStream
- PushbackInputStream
- SequenceInputStream
ByteArrayInputStream constructors
ByteArrayInputStream(byte[] buf)
ByteArrayInputStream(byte[] buf, int offset, int length)
ByteArrayInputStream(byte[] buf) constructor creates a ByteArrayInputStream object to read a byte array.
ByteArrayInputStream(byte[] buf, int offset, int length) constructor creates a ByteArrayInputStream object to read a byte array from index offset to offset+length.
All methods of ByteArrayInputStream are inherited from InputStream.
Methods
int available()
void close()
void mark(int readAheadLimit)
boolean markSupported()
int read()
int read(byte[] b, int off, int len)
void reset()
long skip(long n)
Example: Reading a byte array in the way of an InputStream:
ByteArrayInputStreamEx1.java
package org.o7planning.bytearrayinputstream.ex;
import java.io.ByteArrayInputStream;
import java.io.IOException;
public class ByteArrayInputStreamEx1 {
public static void main(String[] args) throws IOException {
byte[] byteArray = new byte[] {84, 104, 105, 115, 32, 105, 115, 32, 116, 101, 120, 116};
ByteArrayInputStream is = new ByteArrayInputStream(byteArray);
int b;
while((b = is.read()) != -1) {
// Convert byte to character.
char ch = (char) b;
System.out.println(b + " --> " + ch);
}
}
}
Output:
84 --> T
104 --> h
105 --> i
115 --> s
32 -->
105 --> i
115 --> s
32 -->
116 --> t
101 --> e
120 --> x
116 --> t
Basically, all ByteArrayInputStream's methods are inherited from InputStream, so you can find more examples of how to use these methods in the article below:
