Examples of java.io.RandomAccessFile.writeInt()

java.io.RandomAccessFile.writeInt()
Writes a 32-bit int to this output stream. The resulting output is the 4 bytes, highest order first, of val. @param val the int to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readInt()
