+/*
+Quick Overview:
+
+This program writes data into a file named myFile.txt using FileOutputStream.
+- It first prepares a string "Welcome to JAVA", converts it to bytes
+(though it doesn’t actually write it), and writes only a single byte 65 ('A' character) into the file.
+- It uses streaming (byte-by-byte) to write data.
+
+- fout is a reference to the FileOutputStream object.
+
+FileOutputStream → The class (type).
+new FileOutputStream(...) → Creates a new object in memory.
+So fout is not the object itself—it's like a remote control or pointer that lets you
+interact with the FileOutputStream object created by new.
+
+Extra Quick Notes:
+- getBytes() converts the string into a byte array (but here it's not actually used to write).
+- fout.write(65) writes the ASCII character 'A' into myFile.txt.
+- Yes, fout is a reference (not the actual object itself).
+
+This how we use FileOutputstream class to write the data into file
+by how you write data by streaming the data and how streaming a data by converting into bytes
+This is for write data into file using output stram
