In Java, you can use the write method of the PrintStream class to write a single character or an array of bytes to the standard output stream.
Here's an example of how to use the write method to write a single character to the standard output stream:
System.out.write('A');
In this example, the write method writes the character 'A' to the standard output stream.
You can also use the write method to write an array of bytes to the standard output stream:
byte[] bytes = { 'H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd' };
System.out.write(bytes, 0, bytes.length);
In this example, the write method writes the array of bytes bytes to the standard output stream, starting from the first element (index 0) and writing all the elements of the array (bytes.length elements).
Note that the write method does not automatically add a newline character at the end of the output, unlike the println method. If you want to print a newline character after the output, you can use the println method or use the write method to write a newline character:
System.out.write('\n');
You can find more information about the write method and how to use it in Java in the Java documentation.
