Syntax
ByteArrayInputStream.read(byte[] b, int off, int len) has the following syntax.
public int read(byte[] b, int off, int len)
Example
In the following code shows how to use ByteArrayInputStream.read(byte[] b, int off, int len) method.
//w w w . j ava 2 s . c o m
import java.io.ByteArrayInputStream;
import java.io.IOException;
public class Main {
public static void main(String[] args) throws IOException {
byte[] buf = { 65, 66, 67, 68, 69 };
ByteArrayInputStream bais = new ByteArrayInputStream(buf);
byte[] b = new byte[4];
int num = bais.read(b, 2, 2);
System.out.println("Bytes read: " + num);
for (byte s : b) {
char c = (char) s;
System.out.println(s);
if (s == 0){
System.out.println(": Null");
}else{
System.out.println(": " + c);
}
}
