Examples of java.io.ObjectInputStream.readInt()

java.io.ObjectInputStream.readInt()
Reads and returns primitive data of type int read from the receiver @return an int saved as primitive data usingObjectOutputStream.writeInt() @throws IOException If an IO exception happened when reading the primitive data.
