⟩ How do I create an output stream?
On the client side, you can create an output stream to send information to the server socket using the class PrintStream or DataOutputStream of java.io:
PrintStream output;
try {
output = new PrintStream(MyClient.getOutputStream());
}
catch (IOException e) {
System.out.println(e);
}
The class PrintStream has methods for displaying textual representation of Java primitive data types. Its Write and println methods are important here. Also, you may want to use the DataOutputStream:
DataOutputStream output;
try {
output = new DataOutputStream(MyClient.getOutputStream());
}
catch (IOException e) {
System.out.println(e);
}
The class DataOutputStream allows you to write Java primitive data types; many of its methods write a single Java primitive type to the output stream. The method writeBytes is a useful one.
On the server side, you can use the class PrintStream to send information to the client.
PrintStream output;
try {
output = new PrintStream(serviceSocket.getOutputStream());
}
catch (IOException e) {
System.out.println(e);
}
Note: You can use the class DataOutputStream as mentioned above.
